Microsoft is having a one-day sale today, with big savings on Surface Pro 4, Xbox One S, and many other products. And yes, that big Groove promotion that Brad mentioned last night is part of this sale.

Technically, the “one day” sale is closer to two days. It began last night at 9 pm ET and runs through midnight tonight. Savings vary by product, but they will range from 27 to 50 percent. Except in Groove’s case, where the savings are closer to 86 percent.

Here’s a sampling of some of the better deals today.

Surface Pro 4. Microsoft’s previous generation flagship tablet is $350 off and now starts at $849.

Xbox One S. If you buy the Xbox One S Forza Horizon 3 500 GB bundle today, it’s just $229, and you get three free games: The Crew, Just Dance 2016, and Watch Dogs. That’s $100 off, all together.

Video games. Numerous Xbox One games are on sale, from Tom Clancy’s Ghost Recon Wildlands ($39.99, $20 off) to FIFA 17 ($19.99, $40 off) to Watch Dogs 2 ($29.99, $30 off) and many, many others.

In case it’s not obvious, Microsoft’s one day sale is timed to Amazon’s annual sale for Prime members, which requires a $100 annual subscription fee. Google and others are having similar sales as well.
