Price Protectr - probably the greatest thing ever.

Nope, I didn't mispell it. It is what it is. Here's the description from the website:

Get your money back!
There are lots of stores out there that offer price protection policies -- when the price drops on an item you've purchased, they'll refund you the difference. But there's a catch... it's up to you to watch prices.

Price Protectr makes it simple to keep track of your purchases and get your money back. It's free. It's easy. It's free and easy money. How often do you get that offer?
