While PexUniverse.com reserves the legal right set its own product pricing, some manufacturers require internet retailers to display a price at or above manufacturer's established MAP ("Minimum Advertised Price").

Since our price for this product is lower then MAP, the manufacturer does not allow us to display our lowest price until you place the product in the shopping cart. This allows us to continue offering our lowest prices while staying consistent with product manufacturer's policy.

We understand that this is an inconvenience and are continually working with manufacturers to educate them on how MAP affects our customers.

This process does not require you to purchase the product - it can be easily removed from shopping cart if needed.
