Microsoft has permanent cut the prices on the Lumia 950 and Lumia 950 XL smartphones. Also, the unlocked dual SIM version of the Lumia 650 gets a $50 discount down to $149 on the Microsoft Store until August 21.
Microsoft has reduced the price of the 5.2-inch Lumia 950 to just $399, and the 5.7-inch Lumia 950 XL can be bought for $499. Microsoft's previous offer of a free $99 Display Dock with the purchase of either phone has now expired.
If you want to get the Lumia 950 for an ever cheaper price, AT&T has the phone for $298.99 without a contract. However, you will be stuck on AT&T's network for six months until the carrier allows you to unlock the phone.
The current discount for the Lumia 650 on the Microsoft Store site looks like it will indeed only be around for seven days. Cricket Wireless is also selling a version of the same phone for an even lower price of $49.99 without a contract until August 21. However, you are once again stuck with using the phone on its network for six months before you are allowed to unlock it.
