Be Cheap - Why pay more when you can be cheap?

Sometimes the best deals are found by everyday users and submitted to online communities called forums. Here are some of the best:

http://www.slickdeals.net
Slickdeals is a great community, but make sure you go to the "Hot Deals" forum for the best deals!

http://www.fatwallet.com
FatWallet has better sorting and filtering options in their forums, plus they have a nice cashback program. They do make you register before you can access much though.

I'll be posting back as I find more. Feel free to leave any suggestions in the comments.
