So Ebates now has a browser button that you can install, and it will change color and flash if Ebates are available for the online store you're looking at. Cool. Because I experience unreasonable levels of rage when I forget to use Ebates. There's a tab on the right site of the Ebates homepage that will direct you to more info and installation instructions. Seems like a good idea, so long as you're okay with them WATCHING YOU ALL THE TIME. (Kidding?)
If you don't know what Ebates is, I wrote about it here. If you do any online shopping, you really should use it. There's no catch.
