I am designing cpa style pages for some of my products. Example first name, last name, and email on first page, address info on 2nd page, billing info on final I was looking at using 1shoppingcart and a customized code for ease of use, but there are potential issues due to it being a one page cart, so I was looking for cart alternatives that can be used with authorize.net AIM Should I just stick with 1shoppingcart with custom coding, or bit the bullet and go with a real cart? I looked at agoracart, but it does not currently support authorize.net AIM Anyone have experience with using zencart or oscommerce? Do they both support authorize.net AIM, as it is unclear from their websites. At this point I am looking for the most out of box solution if I don't go with 1shoppingcart
