30 dollars 3DS code for 20 dollar Wii U code

Will trade a wii u game download of zelda, mario, pikmin, or wii u party for a year of playstation plus

There's no need to trade - the 3DS and Wii U use the same eShop codes even though they can't share a wallet. The $30 promo code can be redeemed and used on the Wii U's eshop, but the credit can't be split between the 3DS and Wii U - it's all or nothing.

It's even right on the bottom of the promo page: http://club2.nintendo.com/30/

done and done
