Where can I find Final Fantasy games for cheap?

Question

Okay, now keep in mind, I'm from the U.S. and I ONLY have a PS3, so I basically need all the remakes that were made for the first six. The only game I don't want is FFXI, because it's an online game, and I hate online games, especially if it's anything like WoW; can't understand that game if my life depended on it.

Anyway, so I suppose here are the games I need:
Final Fantasy Origins (so I get both I and II - that's right, right?)
Final Fantasy III (I think this is only for the DS, but my niece has a DS, so hopefulllly I could borrow hers while I play it)
Final Fantasy IV (this would be for the DS)
Final Fantasy Anthology (this has V and VI in it, right? And I know this was released in the U.S., so hopefully I'd be able to find it)
Final Fantasy VII (I CAN'T FIND THIS CHEAP ANYWHERE. It's more expensive than FFXIII)
Final Fantasy VIII (Haven't looked for this one yet, but I'm sure it'll be just as expensive as VII)
Final Fantasy IX

And then X, X-2, XII, and XIII are all at Wal-mart, and the first three are used, and they're cheap. So yeah. This was a really long post, and I don't even know if anyone will really reply to this. But yeah, thank you in advance.

Answer 1

Wow, you've really researched this a lot. You can find all of those games, even VII-IX, pretty cheap (used) on Amazon.

Answer 2

ebay is your best bet but final fantasy 7 cheap your crazy the game is a legend it will just rise in price but then again you could get lucky at a yard sale or flea market i guess or if your not doing this to collect look up final fantasy 7 green label

Answer 3

I think you should use p2p (torrents). These are the best way to get every game for free. But the download time is bit irritating when downloading large games. Other wise search for some 2nd hand game seller websites.
