Both games are really hard to find nationwide, with some isolated pockets that still seem to have copies in stock.
The PS2 versions are close to rare, and are demanding high prices on eBay -- used copies sell in the $30 range for both games. Initial title shipments were low, and reorders were weak. There will be folks who say otherwise (like some places still have Rez cheap), but they have not been tracking the title -- I have been trying to find deals on both games since they came out, and it is tough. I ended up getting a used FF1 on eBay for about $28 shipped, and I just sealed a deal for a new FF2 for $29 shipped. This is despite the fact that BestBuy cleared both titles out at one time or another for as low as $4 and some change -- my BB had sold out of them long before they got discounted. My local CompUSA has 2 copies of FF2 for $49, and seems to never want to mark them down.
TRU might have it marked down, but it is unlikley they have any copies left. If u see it for under $20, don't hesitate to buy them.
