I really wanted to save up my money. I was doing so well, refusing things left and right. Yet, I could not refuse this. My PSP-Go is almost out of memory, and I've been meaning to get some more. $39.99 (or $42 shipped) can't be beat, when it retails for about $70 or more (also used Bing, so hopefully I'll get at least something back from that).
I hate to love you, CAG. Thanks OP (it's back in-stock at J&R, by the way).
