Walmart is currently offering a significant discount on high-speed Onn MicroSD Express cards for the Nintendo Switch 2. Using the unadvertised coupon code SAVE3X at checkout, you can grab the 512GB model for just $74.77 or the 256GB version for $36.77.
These cards are essential for the Switch 2, which requires the faster MicroSD Express standard compared to older console hardware. With massive game installs like Final Fantasy 14 taking up nearly half the system’s 256GB internal storage, these high-capacity, high-speed cards are a must-have for any Switch 2 owner.
