ThinkGeek is holding a big clearance sale right now that will put a smile on the face of all the diehard nerds out there. Prices on some items are over 50% off, and can save you big bucks on all of the .

For those of you (in the U.S.) who've been holding off on making the upgrade to Vista there's never been a better time than right now. Vista SP1 is scheduled for release in the early part of 2008, and now there is an exceptional deal on the Vista Home Premium Upgrade over at Best Buy.

If you've missed out on one of our other security software deals, then this is one you may want to take advantage of. I'll forewarn you that this does require a mail in rebate, but in the end you can actually make money from it! Oh yeah, and you must purchase this today if you want to cash in on the rebate.

Google has setup a special page where Checkout users can donate money to their favorite charities. There are 11 charities in total that are supported, including UNICEF, Make a Wish Foundation, and the American Red Cross.

As you witnessed earlier today with the iPod Touch, Amazon is a great source of deals. The real question is how do you find all of the deals that you're looking for without spending hours browsing through their products each day.

We've previously written about the relatively good deal that Newegg offers on ESET security software, but it just got a little bit better.

You've probably heard about CompUSA shutting down all 103 of their stores over the next few weeks, and word just got out that the inventory clearance sale starts soon. As it stands right now the first markdown will be 10% off of everything in the store, and that will be happening on Wednesday, December 12.

I needed two licenses for it, and I decided to just buy the two-year subscription up front so that I could take advantage of the extra savings. In the end my total came out to $103.99, but it was worth it for two licenses and two years of protection from one of the best security companies around.
