If you have any trouble with this plugin, don't contact GetShopped for help.
I had a Gold Cart account which they state comes with premium support. They don't say that this only entitles you to a single question, that it will take weeks for them to get back to you, and that you then have to pay USD$47 for every other email you wish to send them.
My "support token" was used up in just trying to get Gold Cart working - and then I had to pay to ask for help after that. Their response to my query is a "it's not our fault" and then you're left hanging.
I've had much friendlier and more helpful emails from free plugins. Will stay well clear of this one in the future.
