The Nintendo Switch basically necessitates a memory card, and the microSDXC cards it supports can get pretty expensive at higher capacities. That's why it's a great time to buy one with Best Buy's current sale, which prices a 400GB card down to almost half its normal cost.

The SanDisk 400GB microSDXC card for Nintendo Switch is typically $180 at Best Buy, but it's only $100 during this sale, and a free Shutterfly $25 voucher or 8x8 photo book is included as a free bonus. Though other brands and non-licensed cards will also work perfectly fine with your system and can come at lower prices, some of the other models we've seen don't have the same warranty length. This model is backed by a limited lifetime warranty, meaning that if something goes sideways a few years after you purchase it, there is a good chance you'll be able to get a replacement for free.
