DVD Overnight is one of the few stores we have had in the price search that does not have an affiliate sales commission tracking system in place. Stores with affiliate systems pay nothing for participation, we are paid a commission for any items sold through the price search. If nothing is sold then they don't pay us anything.

If a store doesn't have a sales tracking system we charge them a nomimal fee for participation that works out to be roughly an average of the monthly affiliate revenue generated through the price search by all participating stores. The flat rate is designed to be fair to all participating retailers. Sometimes it just doesn't work out to be cost-effective depending on a store's pricing and product selection.
