UPDATED: Disclaimer -
This offer appears to be for existing/previous Surface (Surface Pro 3 and 4) owners ONLY as it requires logging into your Microsoft Account to access. So this is definitely YMMV. Also appears only people who had devices registered on their accounts before May 4th are eligible so no *new* registrations work.
Hello! Just got an email for a great offer for existing/previous Surface Owners - get a current model Surface Pro i5/8GB/128GB for $200 off AND a free Signature Type Cover of your choice (3 Colors)!
For people that like the Surface Pro form factor, and possibly have an older model and need 8GB RAM this is a great deal. Of course if you can work with 4GB, the recent OfficeDepot offer cant be beat.
The offer is listed here and you must sign in with a Microsoft account that has the Surface associated with it (see disclaimer).
Hope this helps someone! Enjoy!
