Sandisk MicroSD Memory: 1TB Extreme $190, 512GB Extreme $80, 512GB Ultra EXPIRED

I show the price at 44.99 for the 400 GB plus shipping. Am I missing something?

Good question, there is a lot of data and research out there showing there is no need to get any extreme or endurance or higher speed cards for a switch. The Nintendo Switch will only write and read at the Class 10 speeds you get from the Sandisk Ultra class 10. Buying a "faster SD" card is a waste of money on a switch. Use those in cameras or high end video gear. It is wasted on the switch. Basically, the bulk of SD cards you see here on slickdeals will ALL work on a switch, and all at the same speed, regardless of how fancy you go. Spend the extra $ on size. 128 is good for a few dozen games mixed between digital and cartridge. 256 is better for more digital use 50 or more games or for epic games that require a lot of data download. 400 is perfect for holding 75+ games
