If you already have the game registered, just upgrade your account to a "Family" account so you can register multiple copies of the same game. Details and instructions are available at clubnintendo.com
@albatross... can I do that? I thought if I tried to enter it, it would still register, but give no points, and invalidate it for anyone else. I haven't had a dupe yet, so I don't know. @marcus... the title/system just tells us the value upfront... I guess you consider yours like "mystery" auctions, thus the variable amount of points? Usually it's for a specific game, so the amount is already known. If so, that's cool, I just want to make sure I'm clear. I was confused by the variable, 20-50. And I don't want to mess with a family acct, I'm only trying to get enough points for one reward, but not buying any new games at the moment, so I thought I'd try here for some. Thanks!
