I am interested in running multiple affiliate programs on one website. Simply because I am attempting to gain more exposure, i.e. the more affiliates promoting, the more sales... One of the programs would be an in house and the other(s) 3rd party program(s). All of the programs, whether it be 2 or 3 or whatever, are compatible with the same shopping cart payment vendor. Or should I say that all of them go through the same payment check out. I currently manage an in house program so manually managing another one or two would not be a problem. I would simply rule out duplicate sales and give the last referral credit for the sale. I can not create multiple websites of the same content for obvious reasons. Unlike if I had a single sales page site, then I could simply create different pages for the different programs. My dilemma is how would I then include all of the different programs' affiliate links' code in the add to cart buttons? There must be some sort of script or something that I can use. Any help would be much appreciated!
