With retail coupons, the retailer absorbs the reductions in price. Manufacturer coupons - great promotional tool to attract new customers, encourage repeat sales and larger purchases, and increase market share. To be profitable, however, coupons most attract a large share of new buyers. Leader pricing - selling one or a few items a deep discount to increase traffic and sales on complementary items. Promotes sales of slower sellers.
Odd pricing is used to denote low or sales prices.
