mkay well you could try ebay or another one of those sites to buy the game :]
Ebay - some right bargins to be had! Currently playing NFSU Rivals that I picked up for less than a fiver and has so far done me 14 odd hours and still only about 50% complete :D:D
Gamestop does have a bit of a problem with PSP games...but they're usually a good source. If you're lucky you can find the good older games on the PSN.
Ebay is the best place to look...
gamestop does have a used section you know? theirs also play n` trade if you want older games chances are you wont find it new.
Ebay or I usually go down to the market as I was looking for Twisted Metal Head On for ages and none of my local game stores had it in but I found it at the market I got it for ? which I didn't mind as it was in perfect condition. I'd be careful buying them from ebay in case the UMD disc case is cracked some people do end up selling them on ebay which won't load into the PSP I always like to check the UMD case and disc before buying. I
Amazon or Gamestop. I don't trust ebay anyways...You sure Gamestop is out of old games? I got a used copy of Metal Slug Anthology there, and it's like 4 years old!
If you are looking for VCS or LCS, just buy them on the PSN, if you have a HUUUUUUGGGEEEE memory card that is.
