As Wii U owners with a 32GB Premium / Deluxe model are undoubtedly aware, that system includes membership in the Nintendo Network Premium Promotion. Once linked to a Nintendo Network ID this applies points to each purchase on the Wii U eShop, and spending an amount that roughly equates to a full retail game brings the reward of a £5 / €5 / $5 credit voucher; even better, that redemption code can be used in the eShop on either the Wii U or 3DS, especially with Nintendo Network IDs and funds now being linked across the systems.
It's always been a limited time deal, however, right from the day it was first announced in 2012. The fine print has made clear that the promotion ends on 31st December 2014, which is one week away at the time of writing. That means this festive period is the last chance to pick up points on eShop purchases. Any points earned will last a little longer, as you have until 31st March 2015 to redeem existing points for vouchers.
So, don't forget to check on your points progress at p.nintendo.net, in case picking up an extra treat will get you one last bonus discount.
