1. This shopping cart system is Category Driven ONLY! ... there is ABSOLUTELY NO WAY of filtering the products! They have created additional features like product TYPES and ATTRIBUTES to enhance the products ordering system, but if you want your customers to sort the products by any other means other than by Name, Category and a few things like Price ... then just FORGET IT!
2. Manufactures are worthless in this system. You can't do anything with them.
2. Vendors are worthless in this system. You can't do anything with them. Admittingly this feature is Beat.
3. No REAL support in the forums ... there are very few real developers working on this thing, and forget about Feature Requests ... out of the hundred or so, only 1 was fulfilled!
4. There are reasons why this thing is free ... is you want a BASIC shopping cart then this thing will work fine, beyond that go somewhere else.
