Not really a thrift store, but the Pawn Shop thread seems to be gone.
Walked in and looked through a few things and noticed Ju-On The Grudge for the Wii, I was pretty sure it was worth something so I called up my brother, and this thing happens to be worth about $40-$50, so I snatched it up! Price was $14 but asked if they could do $10 out the door, which they did.
Getting harder and harder to find good deals and flips at Pawn Shops, as they've taken to checking GameStop and eBay for their prices
