Update 2:

It only took Nintendo a few hours (a pretty rapid turnaround) to resolve the issue with Legend of Zelda game discounts; you can now pick up any and all series titles on Wii U and 3DS with a 30% discount. Hat tip to Benson for the heads up.

Update:

Thankfully, it seems the originally intention of this promotion (as most interpreted it) is to allow multiple discounts on the full range of Legend of Zelda games. Nintendo of Europe has shared a tweet acknowledging a problem, with a fix planned.

Nintendo UK has also confirmed that the fix outlined in that tweet is in relation to the single purchase limit, confirming that this is an error.

Original Article:

Just recently we shared the pleasing news of a range of discounts on The Legend of Zelda franchise games on the Wii U and 3DS eShop, covering every game released on the systems. The deals are available for My Nintendo members, but now that they're live a disappointing limitation has emerged.

When you look at the eShop (with your account linked to the Nintendo Account / My Nintendo) all the games are shown with a discount, but when you go to make a purchase it prompts you to redeem a voucher. It states that it's limited to one use, and sure enough after we completed a purchase with 30% off - The Legend of Zelda: Oracle of Ages, if you're curious - the games all reverted to full price.

We've re-read the official page a few times and this isn't at all clear, so naturally there's some disappointment among those caught out that were hoping to buy multiple games at a discount. We've asked Nintendo for comment and will update this article should we receive a reply.

When it comes to grabbing a discount, then, choose carefully.
