It looks like Bonsai Barber was replaced with another WiiWare game recently. Fluidity (WiiWare) is now available for your Club Nintendo coins... 150 of them to be exact. It will be available until August 19th.
On another note, if you want double the coins for registering New Super Mario Bros. 2 , purchase the game digitally through the eShop and fill out the survey and you can get 100 coins. If you buy the game from a store you'll get 50 coins. As always, make sure you link your Club Nintendo account to your 3DS and you have until 9/20 to register / purchase the game for the coin bonus.
