Hi, I wanted advice, suggestions or comments on intergrating credit card transactions into my web site to handle credit card transactions. I want people to download my game from my web site and pay by credit card. The game will go for $20.00, 10 levels of a 3D adventure game. If you have any companies I can link with, please give me the web addresses. I want people from all over the world to be able to purchase the game through the web site. Thanks.

You could try Plimus - they handle pretty much the whole shebang for you in terms of credit card and supplying the download links etc.

Thanks. I'm also checking out esellerate (www.esellerate.net)

Heres a Page that may be of use.

Another option is to setup a PayPal shopping cart on your site. The fees appear to be somewhat lower than many of those shown here, and more users will be familiar with PayPal (and possibly more likely to feel safe purchasing through them).

I've only sold physical objects this way (Framed Photos), but I would think that software would also work.

FWIW,
Ewan
