B&H Photo has a $379.99 price tag on Microsoft's unlocked Lumia 950 XL, which is the lowest price we've seen for the Windows 10 Mobile smartphone. However, that price won't last for long.

The discount is a one-day flash sale for the 5.7-inch phone, which means you don't have much time to take advantage of this deal. B&H Photo's "Deal Zone" price comes just one day after Microsoft permanently lowered the cost of the Lumia 950 XL down to $499 on the Microsoft Store site.
