Amazon is having another massive digital game sale for the next 2 weeks. Like all Amazon digital sales they will have rotating sales; some last the whole time others only last a few days. The best deal I have seen so far is the Borderlands bundle, if you don't have either game this is great because it comes with both and all the dlc, minus the two downloadable characters. You can check out the deals page here. And the list of what and when things are going on sale here.
