Mario and Luigi: Dream Team Bros. (3DS) is available at The Game Collection for $48.30, inclusive of postage. I checked out the prices at other online outlets and this seems to be the best deal. It is $60.50 shipped at EB Games, $59.95 shipped at DVD Land and $66.30 shipped at Wow Sight & Sound. The next best price I was able to find was $48.99 with free shipping.
