While most pricing is based on cost factors, there are some exceptions．Prestige pricing meanssetting prices artificially high in order to attract select clientele．Such pricing attempts to suggestthat the quality or style of the product is exceptional or that the item cannot be found elsewhere.Stores can use prestige pricing to attract wealthy shoppers.
Leader pricing and bait pricing are the opposites of prestige pricing．Leader pricing meanssetting low prices on certain items to get people to come into the stores．The products so priced arecalled loss leaders because little or no profit can be made on them．The profits are made from otherproducts people buy while in the store．Bait pricing, now generally considered illegal, means set-ting artificially low prices to attract customers．The store, however, has no intention of sellinggoods at the bait prices．The point is to get people into the store and persuade them of the inferior-ity of the low priced item．Then a higher priced item is presented as a better alternative.
