An attempt is made to get you to buy by appealing to your
desire to save money. If you buy without making your own comparison as
to price, quality, and service, the technique is successful.
The supermarket has a special display at the front of the
store: canned peaches by the case (8 cans) for 'only $3.20.' Checking
the shelves where single cans of peaches may be purchased, one finds
the same brand priced at 40 cents per can.
