I've had my eye on Jam with the Band--the European version of Nintendo's Daigasso! Band Brothers DX--for some time now, but I've held off on buying the DS-based music game because of the high cost of importing it.
sendit.com--which thankfully ships to the US--is selling the game for a mere £4.89 (about $7.50). (Even better: Shipping added just $4 to the total.)
Should the game reach my doorstep in a reasonable amount of time and in the promised condition, I'll probably turn to sendit.com later in the year when I buy Last Window: The Secret of Cape West and Professor Layton and the Lost Future.
