The householder can use the small shop when he or she
runs short of small items of grocery, etc.

The small shop will often be open early in the morning
and late at night. The shopkeeper will also allow some of the best customers to
have credit and pay their bill at the end of the week. Special likes and
dislikes of the customers are catered for by the small shop and they will often
carry a wide variety of stock to cover individual needs of many customers. The
shopkeeper will spend a lot of time and trouble to make sure that regular
customers get exactly what they want.

Because the small shopkeeper buys his goods in small
quantities, he does not have the price advantages offered by bulk purchase. The
small shopkeeper may buy, say, 10 or 20 tins of food and has to pay a much
higher price per tin to the wholesaler than the owner of a larger shop, who
would buy the tins of food by the hundred or even by the thousand. For a big
order like this the price per tin would, of course, be much less. The
supermarket can therefore offer its goods at a much lower price than the small
shop because it buys in bulk.

Because the
small shop gives good personal service, customers may have to wait whilst the
shopkeeper is serving an earlier customer, and this can sometimes be a
disadvantage. Because the small shop is small, it cannot carry a large stock
and it may be difficult to see the stock because of poor display.

Because they usually purchase in bulk the supermarket
is able to offer basic grocery items such as tea, sugar, butter, beans, etc, at
a lower price than the small shop.

The supermarket will use loss leaders to persuade
shoppers to enter the shop. Once they are inside it is hoped that impulse
buying by the customers will take place, making them purchase more than they
had intended. Loss leaders are goods offered at an especially low price, and
these goods are usually placed at the rear of the store so that the customers
will have to pass by all the other goods before reaching the loss leaders. As
they pass these goods they will be tempted to buy on impulse. These goods at
the front of the store are those on which the supermarket is making a good
profit.

During the weekdays, when customers are comparatively
few, the store will play slow music to encourage the shopper to linger and buy
more. At the weekend, when the store it busy, quick music will be played to
encourage the shoppers to move quickly so that more customers can pass through
and the store can take more money.

The goods which the supermarket wants to sell quickly
will be placed at eye level where they can be seen most easily by the shopper.
The supermarkets also place highly priced attractive items near to the loss
leaders, in an effort to encourage sales of these items. For example, expensive
biscuits may be placed near cheap tea, or coffee and tins of fruit may be
placed near to expensive tins of cream.

Special
incentives such as trading stamps may be offered to encourage shoppers to shop
during the week instead of the weekend. Most supermarkets have an excellent
display of goods and if he payment tills are efficiently run, a customer can
obtain his or ‘’ er goods quickly and pleasantly. During the last 20 years.
