If you've never heard about www.fatwallet.com, you're about to. This website is completely dedicated to saving you money. It's a collaboration of deals people find either online or at retail stores and share with everyone else. There are tons of different categories. Personally, I just visit the electronics and computers sections.
Just hit up their forums and you should see a "Hot Deals" section, and in there, a bunch of links to different threads. If you don't live in a major city, there might be a lot of deals that won't really apply to you and those are listed as "YMMV" (your mileage may vary) as in....you might not be able to find this deal near you. Since that applies to me...I just look for the online deals. So if you are looking to buy something and are shopping around online, make sure to check in with fatwallet.com first, you might find a good deal on it.
Kind of like the TJMAXX Apple iPad sale...freakin $399 for the 16GB Wi-Fi version. Only certain stores in certain cities were doing this promotion. So if you lived in or near one of these places, YOU COULD HAVE PICKED ONE UP! Even if you didn't want it, you could have sold it on eBay and made yourself a nice easy hundred bucks!
