Best Tech DealsThe best tech deals from around the web, updated daily.   

Update: All of these deals are still available, and still excellent, but we’ll add a mention of this 200GB SanDisk (a capacity that Samsung doesn’t offer) for $54. It was cheaper on Prime Day, but otherwise, that’s a very good deal.

Samsung’s U3-rated microSD cards are some of the fastest and most popular options out there—I have the 128GB model in my own Nintendo Switch—and all four sizes are down to new all-time low prices today on Amazon. If you need extra space for your action cam, smartphone, tablet, Switch, or anything else, these are extremely good deals.
