If you're selling audio books, eBooks and music on your website, you need a method to deliver them. I like digital delivery.
A customer buys and they are emailed the download link for the product. Done.
The challenge, if you're not selling a lot of product on your website, is that it is really expensive to have up a digital delivery system. If you have big files, like audio files, it becomes even more challenging.
I did thorough research and found Vibralogix. Vibralogix uses an entirely different approach to setting up digital delivery. Best of all, it is really inexpensive. It's a one-time charge of $29.95.
