The sale begins tomorrow, 26th January, and lasts until midnight UK time on 9th February.
Dozens of Zelda games, add-ons and themes for Wii U and 3DS are included.
Nintendo is holding the sale to celebrate Breath of the Wild's upcoming release for Wii U and Nintendo Switch on 3rd March. Pick up a Zelda game and you should have plenty of time to finish it before then.
Considering Nintendo's prices can be stingy this isn't too bad if you want any of them
