The pointless middle-men of ecommerce.

A drop shipping store is a web "store" that's little more than a form that forwards your order to a distributor or wholesaler or some other real store. The distributor makes wholesale and ships direct to you, the "drop shipper" pockets everything you paid above wholesale as their cut for deceiving you into believing they were some kind of stock-holding entity when in reality you could have gone to the wholesaler and saved money.

It's a niche rife with scammers, hence most payment processors officially wanting nothing to do with them.
