    • Why don't we show the price?

      When a manufacturer implements a Minimum Advertised Price (MAP) policy, they create limits on the list price that retailers are allowed to advertise their products for. In line with our efforts to continually provide the lowest possible price, we've made it easier for you to inquire about our Exclusive Pricing on these MAP items.
