Coins suck these days. Haven't bothered with it since they downgraded from Club Nintendo. It's like they had a decent rewards program then it went to shit. Might as well not have one.
Not saying this isn't a downgrade from Club Nintendo, but you are denying literal free money because it's not as good as the free money you got in the past. Um, yeah.
About false advertising, the other day a friend of mine bought the Persona Bundle for Persona 5. It was a bundle of DLC for the game, not including the game. That shit was a lot worse, I'll tell you that much.
