A retailer selling its own private$-$branded women's shoes has decided to simplify its pricing by setting a limited number of prices for its shoes. Although the cost of producing the shoes varies among each style, the store has priced each shoe at one of only three prices $$$9,$$$149,$ and $$199.$ The retailer has found that its loyal customers like this because it simplifies the shoping process. A customer who wants to splurge on a nicer pair of shoes may look at the shoes that cost $$149$ and $$199,$ while customers on a stricter budget consider only the $$99$ shoes.

Which type of pricing policy is the retailer using?

Product$-$line pricing

Penetration pricing

Psychological pricing

Skimming pricing

Promotional pricing
