Extended warranties come to downloadable software

You know those extended warranties that they always try to sell you at electronics (and other) stores? Remarkably, the concept has just been applied to downloadable software!

What Is eDS?

eSellerate Download Service (eDS) is an extended download service that you can purchase to protect all downloadable software in your order. With eDS, you will be able to re-download exact copies of the software you purchased, for a period of 1 (one) year after the date of purchase.

It looks like they charge 5% for this service. Wow. Isn’t it a better idea to just have backups?
