Cerizmo allows you to sell file downloads of any kind - software, ebooks, screencasts, digital artwork, forms, documents - anything that can be downloaded! Download delivery is automatic, and you can track all sales in your Merchant Control Panel. It integrates seamlessly with PayPal and you get paid instantly when you make a sale. And unlike other systems which just use "buy now" links - Cerizmo gives you a customizable store with shopping cart, checkout, and payment integration.
