I need to redesign a storefront in WordPress using goEmerchant as the third party order processor. The shopping cart plugins I've found have either been all-inclusive and work specifically with PayPal or some other processor, are too complicated, or just don't work. I need something that will provide ease in setting up products and categories but which can connect to an external checkout system and gateway (goEmerchant). I'm looking for suggestions of shopping cart plugins that will work with minimal customization but give me the freedom to connect to goEmerchant. Perhaps I'm asking for too much.
Any suggestions of plugins to try? Thanks!
