Digital delivery system software advice?



I’m wanting to start a clipart site that lists several watermarked graphics, and upon successfully charging a user’s credit card, sends that user a .zip file containing the final product.

(The vector / print quality clipart they ordered. )

Any advice appreciated!


A quick google search and you could give either Zen-Cart or ZSCart a go.

I have no experience with either, I just tended to build my own from scratch and integrate with paypal.
