It’s Mario Day, an annual celebration of Nintendo’s mascot. It falls every year on March 10th because the date spells out “MAR10,” but you probably knew that already. Even if you aren’t all that into Mario — good luck avoiding him with the upcoming Super Mario Galaxy movie — i t’s an opportunity to save on all sorts of Nintendo-related games and gear throughout the week. We’ve seen deals on Nintendo Switch and Switch 2 games at Amazon, Best Buy, and GameStop (most of which will expire at the end of the day on March 15th), along with some accessories made for those systems.
