For this month? nope, doubt we'll see any soon as well. Mostly see those deals starting in the period Aug-Dec.
But of course MS can always surprise us with a flash deal, so keep your eye on the WC newsfeed. Not sure but the "deals" app MS has in the store could also notify you of any upcoming deals It notifies me about music/game/movie discounts
For the past few years, Microsoft has had a Pi Day special on March 14th, where you can get a year's worth for 31.41 (or 2, I can't remember if they rounded up). I haven't heard anything about them doing it this year, though.
