It is not an easy decision to choose the right shopping cart for your online store. There are 3 choices offered with your Business Hosting and here we link to each cart's feature list.

osCommerce

ZenCart

CubeCart

It's important to try each site's demo to get a feel for the cart, it's ease of use and it's ability to adapt your particular needs.

After you sign up for web hosting, you can access each cart's installation through Fantastico Deluxe in your cpanel.
