I Was wondering why BeFree merchants tend to have short return day or no return days.

Why exactly merchants do not pay for a sale that was generated in day 10, but pay for a sale geenerated in day 2? It is that sales in day 10 do not have value for the merchant?

Andy of TigerDirect, could you explain why do you not want to pay for sales after day 7?

(I ask you because you seem be one of the few merchants to really understand affiliate marketing)
