Nintendo has let details concerning the Nintendo Network Digital Promotion that they announced back in September come out.
This digital promotion gives users points back on all digital purchases they make. For buying any game from the eShop you receive 10% back in eShop credit essentially.
Spend $60 on a full retail game download and you get 600 points. Every time you pass the 500 point threshold you get $5 in credit for the eShop.
Sounds like a pretty good deal to me, but remember this is exclusive to the Wii U Deluxe Set. This promotion starts December 2012 but all purchases made by Wii U deluxe users after November 18 will count so don’t worry about whether you get your November points or not. You will.
