Purchased WP e-commerce Gold Cart plugin, hoping that I would be able to take care of the little things you usually encounter with a WP plugin.
This plugin is HORRIBLE! The code sucks, questions on the support forum are never answered, and the documentation is worth nothing.
Categories of products: I rewrote the grid-view to be able to drill down categories without showing all products. I expected there to be functions to do so, but no.
Shipping: Cannot get shipping to stick. It will default to whatever it finds.
Category images do not stick. Category default view does not stick. Category image size determines the grid size, had to fudge.
DO NOT USE. I repeat: do not use!
