Since purchasing this plugin a couple years ago along with a Gold Cart update, I've had numerous issues with getting the cart to work and display properly. Pagination issues, categories that won't show up, broken images or links, etc, etc. The "premium" support is non responsive and in fact I've only been able to ask one question of them, which never got answered for over 6 months. And the answer didn't even address the issue. Any new questions I have are directed to the community forums, which while helpful on common issues, are unable to respond to less common ones.
The documentation in extremely sparse and much of it is outdated. Most programmers I've contacted either no longer want to deal with this code or will charge exorbitant prices for working with it. That's just to get it to function properly!
For over ten years, I've operated many other websites with various shopping carts that all have their minor issues, but most are well supported and usable. But I've finally come to the conclusion that WP e-Commerce is not a commercial grade shopping cart. Therefore I cannot in good conscience recommend this plugin for anyone serious about having a busy, fully functioning eCommerce website, at least not with the Gold Cart. In my opinion, it's would be money wasted.
