Here at the BGR Deals team, we always watch Amazon very closely to see all of the great sales offered by the nation's top online retailer. Despite how closely we always watch Amazon, the company still manages to surprise us from time to time. Today is one of those times, because there's an Amazon Gold Box sale happening for one day only on Monday and some of the deals are positively mind-blowing. The star of the show is definitely the SanDisk 200GB Ultra microSDXC UHS-I Memory Card, which is on sale today at an all-time low of just $24! There are plenty of other great deals in today's sale though, like an awesome $330 ASUS 2-in-1 Chromebook for just $279, Windows 10 laptops starting at just $335, a $400 Netgear Orbi whole-home mesh system with a built-in cable modem for $284, a 3TB external hard drive for just $83, and plenty more. You can shop the entire sale right here on Amazon, and check out a few of our favorite deals below.
