The Microsoft Store is offering big discounts on Lenovo laptops and tablet hybrids, with up to $350 off selected models. Those who want to take advantage of the offers need to act fast, though: They are are set to expire March 19.

The best Lenovo deal in the sale is by far the Yoga 3 Pro-1370, with a $350 discount. Normally $1,099, this 13.3-inch laptop-tablet hybrid is on sale for $749.99. Powered by an Intel Core M processor, the laptop’s screen flips back all the way behind so it faces outward, with a touch-screen turning it into a tablet in an instant. Windows 10 automatically changes the interface to make it more touch-friendly. The 7.2-hour battery life means users are unlikely to get stopped by low battery when on the move.

Those after a cheaper laptop will want to consider the Lenovo Ideapad 100-15IBY, a laptop with a 15.6-inch, 1366x768 display. The Intel Celeron 2.16GHz processor won’t be playing any high-end games, but those looking to store a lot of photos and videos will be pleased by the 500GB hard drive, capable of housing hundreds of movies. The laptop also has a built-in webcam, DVD writer, Windows 10 and superfast USB 3.0 connectivity. Normally $349, the Ideapad is on sale for $199.

The 23-inch Lenovo Ideacentre 300-23ISU desktop builds the whole computer into the monitor, meaning all a user needs to plug in is a keyboard, mouse and power to get going. The computer comes with a wireless keyboard and mouse, though, so in practice it needs only one power cable connected. The touch-screen PC is powered by an Intel Skylake processor, 8GB of memory and an Nvidia GeForce 920A graphics processor. Normally $849, the Ideacentre is on sale for $749.

Microsoft has recently made a series of price reductions on third-party computers, so it’s a good idea to check the online store regularly. To celebrate Pi Day (March 14), for example, the company slashed 31.4 percent off selected Dell laptops for one day only. The company also recently made big reductions to other Dell accessories and monitors.
