I bought a used Surface Pro 3 on eBay (the i5 256gb version). The surface site says the limited hardware warranty is good until March 9, 2016. This means it is out of the 45 day purchasing period for the Microsoft complete warranty. Are there any options for a similar warranty for this surface? The unit appears to be in excellent condition. Only thing I've noticed is a small bend/dent on the bottom edge of the casing near the keyboard/dock connector. I'm not sure what could have happened to cause that and not break the screen. The seller appeared to be a discount warehouse, so I can't ask about the history. It works well from my testing yesterday, so I have no other concerns about it. Thank you!
