So, you like the Legend of Zelda games or music enough to want to buy them? WONDERFUL!! ^__^ You can find most Zelda games in your local game-selling stores, like Wal-mart or GameStop. But for the older ones, like Link's Awakening, the Oracle games, or even Ocarina of Time, I suggest looking on-line. Same goes for the Original Sound Tracks, as it's highly unlikely you'll find them selling in your average stores.
So I've compiled a list of some on-line stores that sell them. Good luck!
Anime Nation - WW OST & Zelda Album
Anime Castle - lots of Zelda OSTs
Ebay - all Zelda OSTs (many are bootlegs though...)
Zelda Power - all OSTs (No buying, but you can listen to MP3s from all OSTS...)
If you know of a good, dependable on-line store that sells the Legend of Zelda OSTs, pass the link to me and I'll put it up here for everyone to see. :)
