I bought a i5/4gb/128 surface November 2015 from bestbuy, still have receipt. Now, 4 months out of warranty, I'm having a problem that's common, and they would fix free if I was still under warranty (white pressure mark on the LCD)..I'm wondering if it's possible to se them to fix mine? I really would send mine in, not scam. If some1 could do this for me, how much should I pay them.also I'd pay the diff for the 8gb model if possible. Angle the white spot is more common on the 4gb?
