I have a very simple website up, created in iWeb, and it's simple enough to put in the "Add to cart" buttons from paypal, but I can't figure out how to make the customer automatically get a download of the file, rather than me having to email it to them after receiving notification of payment. I just looked around a bit and found bitbuffet.com and payloadz.com, but they both charge money for the service. I'm pretty sure there's a way to do this without signing up for such a service. My mom's website has mp3 products available for download, and as far as I know her webmaster didn't have her sign up for anything like bitbuffet or payloadz. Any help would be appreciated!
