Dump
Dump: To dispose of new product by selling it at or below cost. Most Hobby dealers purchase new product either directly from the manufacturer or through a wholesale distributor. Manufacturers often require that direct dealer accounts and/or distributors must purchase all products -- including those products dealers either do not want, or don't think they can sell -- in order to maintain their direct accounts. To liquidate this unwanted product, Hobby dealers sell it at a discount (dump it) if only to get it out of their inventory.
Throughout the late 90s and early 2000s, the internet (especially eBay) provided an avenue for dealers to dump unwanted new boxes. This was especially true of Pinnacle Brands and Fleer products.
Beginning in 2011, both Upper Deck and Panini America started Resale Price Maintenance programs to combat the (alleged) dumping problem.
