Im selling a full blown php cart script, with multiple currencies (auto updated by xml feed from european bank central), for selling website templates. It also has full paypal link and automaitic download system, so the user is emailed of download instructions and once the page is opened with the download they have a 1hr window to download until it goes. ALSO theres a full admin panel where your designers can upload thier designs, you can control all the pages content etc. And it has a nice design included also. Its also unique, and is not actually used anymore, and im the only person who has the files. You can buy it non-resellers or resellers license, if you wish, contact me if your interested .
