The practice of stamping one price on top of another price has traditionally ranked high on the list of complaints consumers have about supermarkets. Largely due to rapidly rising food prices, opposition to re-pricing ran highest during the 1970's, and numerous attempts were made to legislate re-pricing bans at the national, State, and local levels. Grocers are not unanimous in their opinion of re-pricing. Some contend that the benefits derived are not worthwhile, considering the amount of consumer dissatisfaction that it generates. Others, probably most, say that after a sale they must re-price the remaining stock at the presale level, and many also want to raise prices as soon as they have to pay more for the merchandise they purchase.
