Hopefully not YMMV, but my local Hastings was currently running the B1G1 on used PS2 games at Hastings. They ran this promo a little while ago, and its back. I managed to snag Persona 3:FES and Baroque for about $37.00
what state are you in? was there a sign saying what the dates of the sale were? I just called a hastings in KS and MO and both told me there wasn't such a sale.
Hastings in West TN where I live is doing B1 get 1 for a penny still. It's been going for a few months now. They had Gamecube and Xbox games at B1 get 1 for penny back in March. Didn't see any signs indicating if that was still going on as well.
