Hi, I ahve a fully funtioning site offering users the oppertunity to purchase e guides off my site. I currently use paypal and would like to continue using them, but I would like to let others market my site . And simply track their sals via coupon codes. (Example: guide may normally cost $50 but when user uses a code, it only cost $20) I then know who sent th user to the site, and where to pay commision.
I just need an easy way to track sales per agent on the site!!!
