To put it simply, it's a celebration created by Nintendo Mario fans that takes place on March 10 every year (because according to National Today, “Mar10” looks a lot like the word Mario), making it the perfect day to acknowledge the main character in all his glory. And thankfully retailers like Best Buy see the day as an ideal excuse to bless us with mega Nintendo discounts that we probably won't see again until Black Friday (um, thank you). What are some deals to expect? Major price drops on games like Super Mario Party—currently on sale for $30 from $60—and everyone's favorite racing game (yes, we're talking about Mario Kart 8 Deluxe) marked down to $40 from $60. Or better yet, if you want to upgrade your controller, you can scoop up a Nintendo-themed-wrapped PowerA Wired Controller for Nintendo Switch and a travel case for under $20. Just don't forget these discounts end tonight, so without further ado, here are the five best Mario Day deals to score before it's too late.
