The document discusses three pricing techniques used by retailers: leader pricing where certain items are priced lower to attract customers and boost complementary sales; price lining where retailers offer a limited number of predetermined price points within a category; and odd pricing where prices end in odd numbers like .99 cents to seem less than full dollar amounts. Examples are given of Walmart, Family Dollar, Sears, Sam's Club, and Best Buy using these techniques for movies, toys, DVDs, and other products.
