Starting in October, if you spend $100 on the PSN, you will get $20 dollars back. This is an especially good deal if you’re thinking of upgrading to plus or picking up one of those day 1 digital titles. Like previous promotions this total is cumulative, so feel free picking up items here and there if you want. However, there is no word on if this promotion stacks, so you might not get $40 back for spending $200.
For those looking for something to buy, I strongly suggest looking at our review section or just pick up Spelunker HD.
