I dunno
I was able to find several models that were interesting, the site was easy to navigate, and things were smooth. 2 things I would suggest: 1. Figure out how to setup the checkout process so coins and purchases can be done in the same transaction. Two transactions was fine, but I imagine I will not be the only person to ever try it. 2. Check your links to the files periodically. I tried to download a file and the link was broken. Even after contacting customer support, they also had a broken link. The 2nd link the customer support team sent did.
