Hey, the wife and I are gonna be heading down to King of Prussian and Philly area. Any good spots where deals can be had?

I think I've narrowed down my search to series. Metroid, Zelda, Mega Man, maybe Final Fantasy. NES on up. I'm just rebuilding my collection so, I don't have much. You can see some of what I'm looking for in my bio.

If you know of any good thrift stores, game shops, or others that might have deals, let me know. (I know I could hit up ebay, but it's more fun to shop. )
