well, it is not too cheap anywhere, but I would look online on stuff like ebay (I live in germany, no idea how it is in the U.S.) Also only game disc may be cheaper, but you should have some sort of case for it later :>
Downloading an ISO for your emulator may be free, but not legal if you don't own the game. (In fact having an ISO of a game is only legal if you made it yourself from your own copy and this is relatively easy with any GameCube game).
Ebay is your best bet, but it's not cheap. If you have a Japanese GameCube it is actually cheaper to import a copy of the game from there, possibly because it is less popular in Japan.
In Europe and the US second hand copies may be slightly more expensive than Japan but it's still a lot cheaper than new modern games and arguably give you much more enjoyment.
