Many owners of the Lumia 920, Lumia 925 and Lumia 1020 were not happy that Microsoft decided not to include their phones in the Windows 10 Mobile update. Now Microsoft is offering those owners a chance to get a discount off a new Lumia 950 or Lumia 950 XL by trading in their older device.

Microsoft is offering up to $150 in credit towards the purchase of the Lumia 950 and Lumia 950 XL by either trading in the Lumia 920, 925 and 1020 by mail or heading to a Microsoft Store retail location in the U.S. or Canada. The trade-in offer will last until June 30. If the trade-in is by mail, owners of the older phones will go to a site that deterimines the exact amount of credit they will get, depending on the phone model and condition.

After the phone is traded in, Microsoft will email the owner with a promo code that can be used online to get the discount on the Lumia 950 or 950 XL. The promo code must be used by July 30. Microsoft adds:

To be eligible for trade-in, you must own the qualifying device, device must power on battery must hold charge and not be required to be plugged in to operate, and be in fully functional, working condition without broken/missing components, cracked display/housing, liquid damage, modification(s) or have device warranty seal broken to be considered working.
