In order to turn over aging inventory and make way for more current stock, some products on our site are listed in a "Dutch Auction". In a Dutch Auction, the selling price of a product is repeatedly lowered every day until product is sold out. As a result of the decreasing purchase price the product deal becomes more enticing to other buyers.
Act quickly to purchase at this "special price" before inventory is depleted and the product is sold out.
