hello!
There are a lot of shopping cart free and paid. A great list you can check at hotscripts.com website.
All free shopping carts like OSC, Zen-Cart, CubeCart, etc... are good only for beginners. It is a real headache for developers when you need to implement modifications. You can check them, but I guess that after a time you should to switch to another one and migration projects are not the cheepest 
Personally, I would recommend a Litecommerce as a "light-weight" shopping cart. I have great experience with it. |
