EDIT: Aww geez, that ended fast.
If you're planning on purchasing anything from Amazon before Black Friday weekend, then you can get $5 off a $25 purchase. After going to the page, give them your email and uncheck the box about sharing before hitting submit. Then if you make a $25 purchase now through November 21, the credit will automatically apply to your purchase.
I use Amazon all the freaking time. Seriously. I bought three pairs of underwear on there last week. So if you're anything like me, this might come in handy!
