Blogger Amit Agarwal of Digital
Inspiration (www.labnol.org) has
developed a simple script that makes it easy to use your website to sell files
(such as photos and ebooks). Free to download from here, it lets
you store your files on Google Drive, then uses Gmail to deliver them automatically when a customer pays
via PayPal. If you only have a couple of things to sell, this is quicker and
easier than installing e-commerce software.
