If you don't already know about this site, then I declare you a noob. Cheap Ass Gamer is the number one stop for getting the best price on any game you could ask for. With extensive forums, contests/giveaways, game tracking and trading...this place has it all. And thankfully, every year, they gather all of the different Black Friday/Cyber Monday deals from retailers and put them all together in one neat spot.

Our next list of deals comes from gaming news site Kotaku. I personally check Kotaku daily due to the sheer awesomeness of their stories and updates on the games and topics that I care about. This year, they've outdone themselves and put together a list of deals on not only games, but consoles, HDTVs, and other electronics. Check this one out if you didn't find what you were looking for above.

So there you go people. A short post yes, and only two links. But I think those two combined give out the majority of the deals taking place on Black Friday and Cyber Monday. At the very least, I hope you learned about a killer deal on a game you've wanted for a while.
