Walmart is currently offering significant discounts on high-speed Onn MicroSD Express cards, which are essential for the 256GB-limited Nintendo Switch 2. By using the unadvertised promo code SAVE3X, you can drop the price of the 512GB model to just $74.77 and the 256GB model to $36.77.
While the coupon is intended for new customers on their first three orders, many existing shoppers have reported that the code still works. With modern Switch 2 titles like Final Fantasy 14 demanding massive amounts of storage, these high-speed cards are a must-have upgrade for your new console.
