Script or Host Service to sell 1 Download file at a time?

is there a good script to install on my server, or host service, to sell 1 download file at a time?

I want to sell a .zip, .pdf, or *video* file.

I'm OK with doing it myself, but would rather a good script to install to handle e-commerce and login to access the file once.

Thanks.

Set it up like a regular paysite using CCBill or ECsuite.

Just make sure that you set the membership term to 7 days max to stop password sharing.

or, if you have your own merchant account, or are doing something you can process with paypal, x-cart supports electronic download and automatically handles generating a unique URL for each sale that only gives access for a limited period.

We have a system which integrates with CCBill and other processors
for that purpose. Their system is of course designed for subscriptions,
but we work around that. A better system is possible if you have your
own merchant account.

Clickbank is a processor does single downloads. They aren't as polished
as CCBill, but they seem to work. http://www.clickbank.com/
