This is basically your last week to do any remaining holiday shopping you have left, especially if you want things shipped to you in time for Christmas. With that said, Amazon is offering up a $75 credit with the purchase of a PlayStation 3, 160GB system. The console itself costs $299, so getting $75 Amazon credit is a pretty good deal. The $75 can be used on any shipped and sold by Amazon.com. You can pick up the deal here.
