I'm a fan of Avactis its a paid shopping cart, but its very user friendly and very easy to integrate into any design that you might want to. Its not as full featured as some of the other carts out there but for something reliable, easy to integrate, and easy to learn I think its a very good choice.

My vote goes to ZenCart.

Zencart is the right choice. It's the best shopping cart I ever use right now in my other sites. It's easy to install and suitable for OSCommerce.

I never really used a shopping cart. I'm going to look into it really I don't know what its made for I may sound dumb but what I really mean is like who uses them and stuff. It gets me confused hearing WHMcs and Shopping cart to me WHMcs is a shopping cart but really to everyone else its a Billing System.

Does WHMCS count? It works great for selling web hosting and can be used for more than just that. Great software
