Due to Super Metroid getting a reduced price of $0.30, Club Nintendo is refunding Wii U owners 150 coins while letting customers keep their download code.
The Super Metroid price drop, which begins May 15, is a special promotion for those with a Wii U. Because many downloaded the game in April for 150 coins, Nintendo decided that it would be unfair for Wii U owners to spend their hard earned coins on a game that would soon be available for a measly $0.30. If you exchanged your coins for Super Metroid, you should soon receive an e-mail like the one below.
While corrections like these are not common, it is certainly a win-win situation for Wii U owners.
