Nintendo is celebrating Mar10 Day with a weeklong sale on select Mario games

SAVE 35%: Now through March 13, a handful of Mario games for the Nintendo Switch are on sale for just $38.99 (normally $59.99) in honor of "Mar10 Day" — shop the savings at Amazon, Walmart, Best Buy, Target, GameStop, and in the Nintendo eShop. It's a-that time again, folks: March 10 marks the video game world's annual celebration of Mario Day — get it? Mar10 Day? — an unofficial holiday that pays tribute to Nintendo's beloved overall-wearing, mustache-having, Goomba-squashing plumber. We normally see retailers commemorate the occasion with a day's worth of discounts on Mario-themed products, but this year, Nintendo's decided to extend the festivities all week long: Now through 11:59 PST on March 13, you can score select Mario games on sale for just $38.99 apiece, or 35% off their $59.99 MSRPs. (That's probably a nod to the fact that the Super Mario Bros. series celebrated its *35th* anniversary last September.)  Read more...More about Nintendo, Mario, Super Mario, Nintendo Switch, and Mashable Shopping
