MAR10 Day 2026 Deals Guide: Celebrate Mario's 40th Anniversary with Major Game & Merch Discounts

Editor's Note: This article is a speculative guide based on the anticipated convergence of MAR10 Day 2026 with Mario's 40th anniversary. All deals, dates, and product details are projections for this future event.

Every March, the gaming calendar marks a special occasion: MAR10 Day. But in 2026, this annual celebration transcends its usual fanfare, transforming into a historic retail event. This year, the clever calendar pun aligning with Mario’s name converges with two monumental milestones: the 40th anniversary of Super Mario Bros. and the soaring hype for the upcoming Super Mario Galaxy film. The result is a perfect storm of promotions, offering some of the most substantial and widespread discounts on first-party Nintendo titles seen in years. For collectors, new fans, and everyone in between, the limited-time sales window from March 8 to March 15 presents a golden opportunity. This guide curates the best deals across games, essential hardware, and merchandise, ensuring you can celebrate four decades of jumping on Goombas without jumping through financial hoops.

The MAR10 Day 2026 Event: A Historic Celebration

MAR10 Day, celebrated every March 10th (MAR10 = Mario), has evolved from a simple social media hashtag into a cornerstone of Nintendo’s annual promotional calendar. It’s a day—often stretched into a week—dedicated to the mustachioed plumber, typically featuring themed activities, announcements, and, most importantly for players, sales.

The 2026 iteration is poised to be the most significant yet. It serves as the retail centerpiece for the year-long Super Mario Bros. 40th Anniversary celebrations, a testament to one of the most enduring franchises in entertainment history. Furthermore, the impending release of the Super Mario Galaxy movie has injected a fresh wave of excitement into the brand, attracting new audiences and re-igniting the passion of long-time fans. This unique cultural moment makes the accompanying deals more than just promotions; they are part of a global celebration.

Crucially, these discounts represent a rare chance for consumers. Significant price cuts on Nintendo’s coveted first-party titles are infrequent, with their value often holding steady for years. The MAR10 Day sale, especially one of this magnitude, is consistently highlighted as one of the best times of the year to purchase these evergreen games. The window is short, however, with most confirmed deals active only from March 8 to March 15, 2026, underscoring the need for prompt action.

Top Game Deals for Nintendo Switch & Switch 2

This year’s game discounts are notable for both their depth and their breadth, covering modern hits, beloved classics, and even next-gen titles.

The headline deal making waves is for the latest hardware. Super Mario Party Jamboree - Nintendo Switch 2 Edition + Jamboree TV is listed at $59.99, a 25% discount from its original $79.99 price. Nintendo is promoting this as the first official discount for a Switch 2 title, a major draw for early adopters looking to build their next-gen library.

For those seeking the deepest cuts, a trio of modern classics is available at a staggering 50% off. You can grab Paper Mario: The Thousand-Year Door, Mario Vs. Donkey Kong, and Mario & Luigi: Brothership for just $29.99 each (down from $59.99). These are premium, first-party adventures at a truly accessible price point.

The next tier features some of the system’s most acclaimed titles at approximately 33% off. Look for Super Mario 3D World + Bowser’s Fury, Super Mario Odyssey, Luigi’s Mansion 3, and the digital version of Super Mario Maker 2 around the $39.99 mark. These are cornerstone games for any Switch collection.

Beyond the round numbers, several standout value picks exist. Super Mario RPG has been spotted for as low as $38.90, while the strategy crossover Mario + Rabbids: Sparks of Hope presents an almost unbelievable opportunity at roughly $5.99—a 90% discount that is arguably the sale’s best value proposition.

Essential Hardware & Accessory Discounts

While games take center stage, one hardware accessory deal is crucial for Switch 2 owners. The Nintendo Switch 2 256GB Memory Card is discounted to $39.99, a 33% saving from its $59.99 MSRP. Given the larger file sizes expected for next-gen titles and the console’s base storage limitations, this high-capacity, officially licensed card is a highly recommended purchase to expand your digital library.

It’s worth noting that all the game deals mentioned are confirmed to be compatible with every Nintendo Switch model, including the Original, Lite, OLED, and the newer Nintendo Switch 2. For other peripherals, such as Mario-themed Nintendo Switch Pro Controllers, Joy-Con, or carrying cases, it is advised to check individual retailer pages during the sale period, as additional, unadvertised markdowns on hardware bundles are common.

Where to Shop: Retailer & Digital Store Guide

Navigating the sale is straightforward, with promotions running concurrently across major retailers.

For players who prefer physical copies to adorn their shelves, the key destinations are:

• Amazon
• Walmart
• Best Buy
• Target

These retailers will carry the discounted physical game cartridges, and they are also the primary outlets for Mario-themed merchandise, toys, and apparel that may be part of the anniversary promotions.

For instant gratification and digital downloads, the official storefronts are your go-to:

• The Nintendo eShop: Directly on your Switch console, offering immediate access to all discounted digital games.
• My Nintendo Store: Nintendo’s online hub, which sometimes features exclusive digital items or physical collectibles not found elsewhere.

A final piece of advice: while the core discounts are standardized, it is always prudent to perform a quick price comparison between retailers. Some, like Best Buy with its My Best Buy membership or Amazon with limited-time lightning deals, may offer additional incentives, exclusive bundles, or slight variations in pricing that could net you an even better bargain.

MAR10 Day 2026 is not just another sale; it’s a landmark event in gaming retail. The alignment with Mario’s 40th anniversary has compelled Nintendo and its partners to offer unprecedented access to its legendary library. From the historic first discount on a Switch 2 game to the jaw-dropping 90% off on acclaimed titles, this week-long event is a must-shop moment for every type of player. These deals provide the perfect foundation for celebrating Mario’s past, present, and future. With offers this significant, your mission is clear: power up your console, visit your retailer of choice, and secure these legendary games before this historic sale warp pipe closes on March 15.
