I have found a great FREE php script that allows digital downloads from your site either by using buttons of your own or using basic shopping carts like CoffeeCup shopping cart creator. The script is simple with just a few settings, it provides an email to the customer with the download as an attachment as well as an encrypted link to the download file which you can set to be available for a period of your choice. This script seems to be very secure with inbuilt checks provided to make sure that the product has been paid for. I am happy to provide anyone with the script if they want it.

You can find out more information and request me to email the script from my blog on my website. You will find the blog listed under "other information" as "Fardon from down under"
