Cripes, man! Where in bumblefarb do you live?!?!
I'd try used game shops and half (they definitely have it in stock!) or ebay. If you are talking about the GBA version, I think it has been OOP for a while (picked my copy up at Circuit City for $10 on clearance almost two years ago I think). If you're sure you want this title, you may want to search for the others (Harmony of Dissonace and Symphony of the Night) at the same time.
