I want to start an online shopping cart. It will feature different products and not services, so I need an affiliate software that can automatically calculate how much an affiliate receives for referring a sale of a product. Each product will have a different price. I will most likely be using Interspire Shopping Cart, or Wordpress e-commerce. Thanks for the tips.:44: Edit: I just read on ISC features list that it has an Affiliate Tracking feature. Has anyone used this?
