If you are a member of the Windows Insider program in Germany, you might be able to get a discount on the new Lumia 950 and Lumia 950 XL smartphones. Microsoft is sending emails to those members informing them of this €50 price cut on these phones for a limited time, plus a way to get a couple of extra accessories.
The special discount is apparently for unlocked phones sold through T-Mobile Germany. This offer means Windows Insiders in that country can buy the Lumia 950 for €549 instead of €599, and the Lumia 950 XL for €649 instead of €699. It also includes a way to get a free Display Dock for those phones along with a free Mozo case. The offer ends on December 13.
