Over the weekend Samsung brought us one of the best Samsung Galaxy S21 deals we've ever seen, and now it's been extended to run through today (March 29) as well. 

Until the end of the day, Samsung has its unlocked Galaxy S21 phones on sale from $99.99 with trade-in. That's one of the best Galaxy S21 deals we've seen all month. (Note that the amount of the trade-in credit depends on the phone you trade in, with newer fans commanding the biggest return.) Plus, you'll get up to $100 Samsung credit that can be used toward add-ons with any phone purchase.

In our Samsung Galaxy S21 Plus review, we found the phone offers a fantastic display, powerful cameras, and an overall refined smartphone experience. On the hardware side of things, you get a 6.7-inch (2400 x 1080) display, Snapdragon 888 CPU, 8GB of RAM, and 128GB of storage. Rear cameras include a 12MP wide (f/1.8), 12MP ultra-wide (f/2.2), and 64MP telephoto (f/2.0) with 3x hybrid zoom/30x digital. There's also a 10MP front camera and support for 8K video recordings at 24 fps. 

In our tests, we found that the S21 Plus' display is great for watching movies, ogling Instagram pics, and playing games. Meanwhile, its photos are flush with colors and detail while delivering a nice upgrade over its predecessor's photo capabilities. In our battery test, we got 9 hours and 41 minutes, which beats the S21, but falls short of the S21 Ultra's 11:25.

Samsung's current sale applies to any S21 Plus phone, but act fast because it ends end of day Sunday.
