Duplicate credit card charges

Just wanted to make people aware that when you order off of Stardock's website and you get an error that states that there was something wrong with transaction, don't keep trying. Somehow, their billing dept will keep charging your credit card each time. I got hit 5 times just to order Fences 2.0 to use on one computer. They really need a better system or inform people on that payment screen not to keep trying. The error gives the impression that there is just a technical issue with the server, but it does not indicate whether the credit card failed or was processed.
