This really, really is. Yodobashi Camera is one of the largest retailers in Japan, and boy oh boy does it ever have a deal for you!
This branch is offering The Legend of Zelda: Spirit Tracks for ¥480 - that's obviously less than one ¥500 coin ($5.80). It's a steal. Never really played that much of Spirit Tracks as I couldn't get past the Link-on-a-train business. (Is it any good?) But at this price, I'd totally pick it up. This is less than a lunch at McDonald's.
Sale runs until April 22.
