Free is a good word, firstly. Second, it works if you follow the instruction provided. I have used this cart on several customer websites, and they have all been impressed with it's ease of use and functionality.
So far as I can tell, no way to change the quantity on hand of an item. Say you only have one widget to sell. Well, if someone inputs 2 on your site, you have a bit of a problem. Disclaimers can fix that though.
