Selling Digital Goods - Paypal - Easiest Way?

[eluser]mikka23[/eluser]
I am trying to selling templates on my website. What would be the easiest way to go about this? Is there any existing scripts I can adapt? Has someone done something similar using codeigniter?

I basically want to upload the zip for the template and have a buy it now with paypal button which emails them the template zip once there payment is made.

This tutorial may help you - Its not selling products but selling member access. Hopefully you can get an idea from it though. It uses the PayPal IPN (instant payment notification).
