Costco YMMW In Store Only Clearance SanDisk 256GB microSDXC Card for the Nintendo Switch, 2-pack for $19.97
This was previously front page +88 at $29.97. My warehouse still has a couple dozen of these. I did a rebuy/return since I did not have the old receipt for a price adjustment and it worked fine. My warehouse is Merrillville, Indiana. Link to the online product is below for reference. Still selling at $90.00 on the website. Photo attached.
And, just in case anyone is concerned about compatibility, these work in anything that takes Microsd (and accepts this size card). They are not limited to Nintendo Switch. They just carry that logo. I am certain that is why they have not sold out already.
