Supermarkets use a number of persuasive strategies to
encourage the shopper to purchase more items. I definitely find supermarket
offers very tempting, and often buy much more than I intend to, for example, when
I go to the supermarket just to buy milk and end up spending around £10. A
tactic that supermarkets use to encourage shoppers to spend more is to locate
essential items in the middle of the store or along the back wall, so shoppers
have to walk past other tempting offers in order to get to the milk. Also, items
on special offer tend to be placed at the end of every aisle, which makes it
hard to reach the milk isle without noticing, and being tempted by, the special
offers.
This can be explained by the ‘smart shopper feeling’
phenomena (Shimp and Kavas 1984). The excitement about ‘getting a good deal’
creates an ego-expressive emotional response and the shopper may feel proud
that they have managed to purchase the product at a cheap price. Research by Schindler
(1988) supports this. 111 female participants were asked to describe a recent
purchase where they spent over £20. They had to report the price that they paid
for the item, the reference price (the price most stores charge for the item)
and how satisfied they felt with the price they paid. Finally, they had to
complete a questionnaire to see how responsible they felt for the price they
paid for the item. Results showed that price satisfaction was correlated with
perceived responsibility, therefore, shoppers felt more satisfied if they
believed they had got a good discount and were responsible for finding the
discount.
Therefore, ‘smart shopper’ feelings will be increased if the
shopper feels they have found a good deal, and they will be likely to purchase
even more items on special offer to enhance this smart shopper feeling. Interestingly,
Kelly’s (1967) co-variation theory suggests that if shoppers feel like they are
receiving a discount that not everyone else is receiving, their smart shopper
feeling will increase further, making them more likely to spend more money in
the shop. Thus, supermarket reward schemes that send customer’s money off coupons
by post will enhance smart-shopper feelings, as the customer will feel like
they have been sent a special discount. So, they will be more likely to buy the
product and use the voucher, even if they do not actually want the product.
Another sneaky yet effective technique used is price
establishing. This is when supermarkets claim that products are being sold at
bargain prices, when they are actually being sold at the standard rate. For
example, Tesco claims to have a ‘big price drop’ on certain items. However, to
enforce this, they put the price of the product up for about a month and then
lower it back to the original price, claiming that it is a big price drop. As
long as the higher price is enforced for at least 28 days, then it is legal for
supermarkets to do this. Other offers also exist that do not actually save the
shopper any money or, in some case, loose them money. An example of this is
shown in the picture below. Robinsons squash is being sold for £1 and is on
offer: ‘any 2 for £2’. Special offers advertising acts as a subconscious
trigger that attracts attention and causes people to only look at the special
offer price rather than the price per unit. Therefore, they do not notice that
purchasing more than one item will not save them any money. The yellow background
label that accompanies special offers also catches the shopper’s attention,
causing them to look at how many products they need to buy in order to get the
special offer, rather than looking at individual unit price.
This special offer saves the customer no money at all, but surprisingly most people will not notice this and buy 2 bottles because they assume it will be better value.
This shows all the special offers located at the ends of aisles, which makes it more likely that customers will see them.
