I used Craigslist and got a brand new one for $100 on Friday night. It would be $97 w/ tax in a store if they had them..so i paid $3 extra. Not too shabby.
buy it online...amazon would be one of the best. i use that site often for stuff i have trouble finding in stores.
I remember when I wanted to buy GH3 a few months ago and that night I bought it, I had to go to 5 different stores to find it for the Wii. The PS2, PS3 and XBOX360 versions were all over the place, but not the Wii. So I know what ya mean.
