Walmart is currently offering a secret discount on Onn MicroSD Express cards, the essential storage upgrade for your Nintendo Switch 2. By using the code SAVE3X at checkout, you can slash the price of the 512GB model to $74.77 or grab the 256GB version for just $36.77.
With the Switch 2’s 256GB internal storage filling up fast—especially with massive titles like Final Fantasy 14—this is a must-have deal. The code works for both new and many returning customers on qualifying orders, making it a perfect time to expand your console’s capacity.
