Just used a code like this to buy an AppleTV a couple of weeks ago, but it's good for anything else as per their terms. Good thing Staples doesn't regard the Apple TV as a computer.

If sign up to be on their email list you'll get coupons like this and more. :clap:

Aside from the fact that the AppleTV is out of stock!
