Before it sells out, pick up the best value 256GB microSD Express card for the Nintendo Switch 2 at Prime Day sale

With Amazon Prime Day 2025 now well underway, we've seen some great deals emerge on our favorite tech products. But there are a few recent releases that are too new for discounts and, in some cases, still too hard to actually get your hands on, thanks to supply and demand issues. Enter microSD Express storage cards for the Nintendo Switch 2; they are a much sought-after item, with prices rising rather than falling, but there is one microSD card that is shining above all at the moment for availability and price.

The official 256GB Samsung microSD Express card for Nintendo Switch 2 is $59 at Walmart, and also the same price direct from the Nintendo store. This is currently the best value 256GB microSD card available to purchase, with the next closest price being $74 for a SanDisk 256GB microSD Express card direct from SanDisk. It's impressive how popular these storage cards are right now, and it's all due to the popularity of Nintendo's latest handheld games console.
