US retailer BestBuy is offering a 20 percent discount on Nintendo eShop prepaid cards.
Available via stores or its website, the discount is available now until friday, December 27, and applies to all three prepaid card values.
The 20 percent discount means you can get a $20 prepaid card for $16, the $35 card for $28, and the $50 card costs $40.
With most retail games on Wii U and 3DS also released as eShop digital downloads, this effectively means you can get almost any game for the two consoles this Christmas at a 20 percent discount.
New eShop games released last week included Shinobi, Streets of Rage, Castlevania and NES Remix.
