Abstract: - The current COVID-19 pandemic affects all segments of the economic system. In many countries,
the governments have announced a country-wide shut down and adopted various COVID-19 preventive
measures to control the spread. The public health and economic crisis change consumer behaviour. People
reduce shopping frequency and shift to stores closer to their homes. This directly affects the business sector.
The goal of this research is to examine factors influencing the purchase decision of flea-market consumers.
This research implements a mixed-method vendor survey to study the impact of the COVID-19 crisis on the
purchase decision based on four factors in the marketing mix, which consists of product, price, promotion and
place. For flea markets in Thailand, the place has no statistical significance. Understanding consumer behaviour
can increase selling channels for vendors. In addition, online selling is not only an option that helps vendors to
increase their sales, but also a way to survive in the COVID-19 crisis.

1 Introduction
The Corona Virus Disease (COVID-19) pandemic
has drastic negative impacts on the global economy,
both domestically and abroad. In the COVID-19
crisis, small businesses have taken the direct impact.
In the United States, many employees had been laid
off and some small businesses had been closed just
a few weeks into the crisis [5]. In Europe, the start-
up industry which is the most important driving
power in the economic sector has received a lot of
negative impact from the COVID-19 pandemic [15],
[16]. One important thing that helps control the
crisis is the movement’s control order of the
government. In Malaysia, after the announcement or
the order, the income of small enterprises decreased
dramatically because the involved supporting
sectors such as retails and transportation had been
closed [12].
The crisis has affected progress towards every
sector of Thailand and the government has
announced a country-wide shut down and applied
various steps to control the spread of COVID-19.
The period of lockdown has caused the mental
health problem and led to some symptoms of
depression and anxiety. This impact becomes a
major obstacle to achieving the Twelfth National
Economic and Social Plan of Thailand that
emphasizes economic growth in terms of investment
for both public and private sectors. The plan is to
enhance community self-reliance, stimulate
entrepreneurship and promote small enterprises
[24]. The most important impact of the crisis is on
consumers, the smallest sector that affects every
sector of the economic system. To endure the crisis,
people think differently, live differently, and buy
differently. They reduce shopping frequency, buy
from stores closer to their homes and change the
factor of purchase decision. A flea market is an
alternative marketplace system that serves specific
needs of people and is embedded in the Thai
experience for a long time. The changes of
consumer attitudes, intentions and purchasing
patterns could be permanent and this is a direct
impact on the flea market economy. Even though
the COVID-19 crisis continues to develop
gradually, by understanding the changes of
consumer behaviour that are happening now, we can
consider what vendors should do today to prepare
for the future.
2 Literature Review
A market is a place where people gather to buy, sell
or exchange products; however, the definition of
flea market has changed over time and differed from
place to place. Hansson and Brembeck [13] define a
flea market as a place, a building, or an open space,
where vendors sell a variety of products to different

target groups of customers. Flea markets are
operated by various types of organizations, not only
local government organizations. The proliferation of
flea markets is an indicator of a local economy [8].
In this COVID-19 pandemic, fruit and vegetable
markets were significantly impacted [20]. The
purchase decision is a decision-making stage of
consumers that leads them to purchase a product or
service. The purchase decision is influenced by the
quality of product and service, the price, and the
situation [7], [21]. The quality affects the customer
satisfaction that can lead to the brand loyalty [14],
[29]. The impact of the price depends on the
consumer income and the cost of living [3].
However, the price can be varied and depend on
places and inventories [9]. The response of
consumers to the simultaneous change of price and
package size increases the market tactics of sellers
[28]. The decision can be interrupted due to
unexpected situations such as a time of scarcity in
the COVID-19 pandemic [19]. There are five roles
involving this purchase decision: an originator, an
influencer, a decision-maker, a buyer and a user
[26].
There are more than 1,500 flea markets across
Thailand with various types such as wet markets,
floating markets, and former markets. Flea markets
are major points for food and product distribution in
Thailand. Consumers can easily find a flea market
near them. Some of the flea markets are large and
some are smaller. Some offer general merchandise
while others specialize in one kind of product, like
antiques or local products. In 2009, Janepraphapong
found that the price factor has the highest influence
in purchase decisions of customers at flea markets in
Mae Phrik District, Lampang Province. For a flea
market in Muang District, Nakhon Ratchasima
Province, not only the price is the most effective
factor in the purchase decision, but also the
closeness of flea markets and customers’ homes
[17]. In 2012, Thongrawd and Saninmool found that
all marketing mix factors had an impact on purchase
decisions of customers in night markets in Bangkok
Metropolitan [25]. For Thonburi Market (Sanam
Luang 2), the largest market in the Thonburi side of
Bangkok, the purchase decision of customers
significantly depends on the variety, standardization
and quality of products [23]. Moreover, customers
value the appropriate pricing for products and their
decisions are also influenced by the market location
and promotion. In a competitive market where
vendors sell similar products, an effective sales
strategy is very important to help increase sales and
profits [1], [2], [18].
3 Research Methodology
An acceptable tool used in marketing to study the
consumer behaviour in purchase decisions is the
marketing mix. It consists of four key factors
relating to the marketing of a product or service,
which are product, price, place and promotion. The
product is a good or service offered by a vendor to
consumers. The price is the cost that consumers pay
for a product or service. The place is where vendors
sell a product, e.g., a flea market. The promotion is
how vendors communicate and reveal a product to
consumers. The marketing mix is a key factor in
buying and selling processes and can be changed
depending on the impact of political, economic and
social situation on the market system [6, 18, 21].
The pricing and promotional strategies, especially a
quantity discount, are effective marketing [27]. The
price tag presentation on a new product combined
with a discount can stimulate the purchase decision
[4].
The mixed-method research consists of analysing
data by using both qualitative and quantitative
methods. We conduct focus groups for qualitative
research and questionnaires for quantitative
research. Since the survey questionnaires in our
research are based on Likert scale, the methodology
in the quantitative part is the nonparametric
statistics consisting of the Mann Whitney U test and
the Kruskal-Wallis test [10, 22]. The Mann Whitney
U test is a method to compare two independent
samples drawn randomly from the population. The
Kruskal-Wallis test is a method to compare two or
more groups of independent samples of equal or
different sizes.
We examine the purchase decision of customers
in five flea markets in a north-eastern (Isan)
province of Thailand based on the marketing mix.
Results from this research are intended to
complement the future plan of vendors.
4 Research Results
The survey is conducted in a north-eastern (Isan)
province of Thailand. There are five major flea
markets in this province: flea markets A, B, C, D
and E. The detail of each market is as follows. Flea
market A opens on Sunday and Tuesday from 3pm
to 9pm, and has a capacity to host approximately 70
vendors. Flea market B opens on Wednesday and
Thursday from 3pm to 9pm, and has capacity for 30
vendors. Flea market C opens on Wednesday from
3pm to 9pm, and has a capacity of 20 vendors. Flea
market D opens on Friday from 3pm to 9pm, and
has a capacity to host approximately 40 vendors.

Due to the COVID-19 outbreak in the province
and the Thailand government measures, the flea-
market functionality and customer behaviour have
changed and vendors receive the direct impact from
the changes. This research implements a mixed-
method vendor survey to understand the impact of
the COVID-19 crisis on flea-market dynamics and
demand for products in the province.
Vendor Perceptions on Customer Purchase
Decision
Flea markets in the province have compiled the
government preventive measures as follows.
1. The entrance and exit must be specified and
everyone passing the entrance must be
screened for body temperature.
2. Every person entering the market must wear a
facial mask at all times.
3. Everyone must maintain social distance at least
1 meter. Every flea market must determine the
stalls’ position to decrease crowding and the
possibility of being infected. Every dining area
must manage seats at least 1 meter apart or
have a partition between each table.
4. Every flea market must provide a hand
washing station or 70% alcohol gel at service
points, e.g., entrances, exits, and payment
points.
5. Every flea market must regularly clean the
entire market every day. For toilets, tables,
seats and all surfaces of service must be
cleaned even more often, e.g., between 2-4
hours.
6. Every flea market must provide information
about eating hot food and using a serving
spoon (own spoon) or disposable serving
utensils.
7. Every flea market must determine if the market
is overcrowded, and limit the amount of
customer service interactions.
8. Every stall must set the plastic partitions
between customers and products to prevent
saliva or other secretions falling into the
products, and avoid touching money directly.
Using payment methods via QR code or
internet banking is recommended. In addition,
the product preparation and handling zones
must be separated.
9. Every flea market must apply the efficient
waste management consisting of collection,
segregation, storage, transportation, treatment
and disposal of waste appropriately. A janitor
must wear an appropriate protection uniform.
Permanent gloves must be carefully washed
and dried after using them. Disposable gloves
must be left in mixed waste bins. After the
gloves are taken off, the janitor must wash
hands up to elbows with water and soap. All
cloth must be cleaned or thrown away after
using.

However, these preventive measures cannot help
vendors to increase their sales and the COVID-19
pandemic still has highly impacted on these flea-
market dynamics. Most products in the flea markets
are deli and fresh food.
Fresh food and Deli are compared using Mann
Whitney U test. The null and alternative hypotheses
are

The test statistic is equal to 2536.5 and the p-
value equals 0.0000. At 5% level of significance,
there is a statistically significant difference between
the fresh food and the deli. From the data, the sales
of the deli is higher than of the fresh food.
Therefore, most customers prefer ready-to-eat foods
more than foods that need further cooking
processes.
To examine customers by genders, we conduct
the Mann Whitney U test,

The test statistic is equal to 8288.5 and the p-
value equals 0.0000. At 5% level of significance,
there is a statistically significant difference between
the male and the female. We found that women
come to flea markets more than men; moreover,
most male sold products are bought by women.
Next, we analyse the customer behaviour in
vendor point of views by using the marketing mix,
which consists of product, price, place and
promotion. From Kruskal-Wallis test,

Not all are equal, where = 1, 2, 3, 4.
The test statistic equals 37.62 and the p-value
is 0.000. Therefore, there is sufficient evidence of
significance that at least one differs from the rest
at 0.05 significance level. By using Bonferroni
procedure, we found that there is insufficient
evidence of a significant difference among product,
price and promotion; however, there is a significant
difference between these three factors and place as
shown in Figure 3.
Fig. 3: The relationship between the four factors in
marketing mix and the purchase decision of
customers in the flea markets.
The researcher conducted the quantitative
method by using the Mann Whitney U test and the
Kruskal-Walis test and the summary of the findings
is shown in Table 2.

According to Table 2, the p-value less than 0.05
is statistically significant different. It indicates that
there is a difference in the customer preference
between fresh food and deli at the 5% significant
level. Similarly, there is a difference in the customer
gender between male and female at the 5%
significant level. In the 4-factor of the marketing
mix, the p-value less than 0.05 is statistically
significantly different among these 4 factors. It
implies that there is at least one factor different from
the rest on the purchase decision of customers at the
5% significant level.
The overview of customer behaviour in the flea
markets is that customers decide to purchase
products by themselves and on average they spend
50-100 baht in the time interval 15:00-19:00 of day.
Vendors at flea markets are affected by the COVID-
19 crisis because of the change of customer
behaviour and the preventive measure, while only a
small number of vendors can adapt to the situation
by starting online sales.
However, for some vendors whose target groups
are elderly persons, online sales may not be a good
option because many older adults have never used
the internet or do not have internet access at home.
For instance, betel nuts are products for older adults

so to increase sales by online platform is almost
impossible. Even though almost all customers in the
flea markets have mobile phones, many of them
cannot afford smartphones with a performance to
access internet or internet package. Scan to Pay
allows customers to scan a QR code at any retail
store and make a payment; in addition, it can reduce
the risk of COVID-19 because of no touching
money bills. However, because of the internet
accessibility problem, it cannot help decreasing the
risk. Even though the trading still happens in this
time period, the sales have decreased dramatically
compared with the period of time before the
COVID-19 crisis.
According to the culture of north-eastern people,
flea markets are not only places for buying goods,
but also places for hanging out with their friends
and families. The COVID-19 crisis makes them less
face to face communication and far apart, especially
elderly people.
5 Discussion
The deli and fresh food have highest sales among
other products in the flea markets; however, the
significant result in the Mann Whitney U test
indicates that there is a difference between these
two. In addition, the vendor point of view on the
customer behaviour shows that most consumers in
the flea markets prefer deli. Therefore, a new vendor
in flea markets should consider selling deli foods.
Moreover, farmers who want to sell fresh products
should consider selling to deli vendors instead of
selling to customers directly. This suggestion is
from the vendors in the five flea markets.
The majority of customers in flea markets are
female; moreover, most male products are also
bought by women. This is due to the fact that in
Thai culture, especially Isan, women remain to
handle household jobs and take care of everyone in
their houses according to the group interview. Thus,
vendors should take into account the needs of
women when they supply goods.
The location of a flea market does not have an
influence on the purchase decision of customers
because most customers travel to flea markets by
their own vehicles which are cars and motorcycles.
As long as vendors can meet three factors, product,
price and promotion, then they can sell their
products at any flea market according to the group
interview.
Since the average price of sold products is in the
range 50-100 baht, vendors should sell products
whose prices are less than or equal to 100 baht
because a customer can easily make a purchase
decision on a product in this price range. Flea
markets can be a place for a person looking for a
secondary occupation because most customers make
purchases at flea markets in the time interval 15:00-
19:00. According to the group interview, the reasons
for high sales in this period are mainly due to good
weather, after work and after school. In [25], all
factors in the marketing mix, product, price, place
and promotion, affect the purchase decision of
customers in Bangkok flea markets; however, our
result shows that all factors except place have an
impact on the purchase decision of customers in
flea markets in the north-eastern (Isan) province of
Thailand
6 Conclusion
The factors influencing the purchase decision of
flea-market consumers are product, price, and
promotion. Even though flea markets have complied
with the preventive measures as follows: screening
body temperature, wearing facial mask, maintaining
social distance, installing hand washing stations,
cleaning service areas and surfaces regularly,
limiting the amount of customer service
interactions, being cautious in touching products or
money, and applying efficient waste management.
Following each wave of COVID-19 in Thailand, the
sales of flea markets always decrease. The country-
wide shutdown that the government has announced
in the COVID-19 pandemic requires people to be
able to stay outdoors between specified hours. This
affects the living of Thai people and the opening
period of flea-markets in Thailand. The shortened
opening time has become the limitation of this
study.
Selling products online can help vendors to
increase their sales and endure the COVID-19 crisis.
Now there are many online platforms that can be
used, for instance, Facebook, Instagram, Line,
TikTok, etc. There are also popular e-market places
in Thailand such as Lazada and Shopee. Vendors
want to have online sales; however, not every
vendor can start selling products online because it is
more than setting up a website and uploading
images, especially, elderly vendors. This issue is
often discussed among elderly vendors.
In the current report of WHO about the COVID-
19 pandemic, the virus that causes COVID-19
changes over time, that means it is impossible to
expect the same as before the crisis. Every sector of
the economy around the world is affected and this
leads to changes in how businesses transform and
consumers respond [11]. Not only in Thailand, but
also in other parts of the world the income of small

businesses is decreasing and owners of businesses
try to find the best way to survive in this crisis [5,
16]. So, every vendor in flea markets must
transform themselves to survive and live with
COVID-19. Online selling is an option that helps
vendors to increase their sales; however,
understanding consumer behaviour is a key factor to
help vendors come up with new selling strategies
and to survive in the COVID-19 crisis.
Now the COVID-19 situation is getting better
and the government has relaxed the COVID-19
control measures. Flea-markets are almost back to
their normal stage; in the meanwhile, many vendors
have adjusted to sell products online. The scope for
the future study can be specified to flea-markets
vendors.
