Okay, so I spilled wine on my laptop a few months ago, and though it was still working, the power button had lost its functionality. I knew that as long as I didn't shut it down, I could ride it out. Well, my girlfriend shut it down accidentally a few weeks ago. Apple says it's going to be $700 to fix it. I was going to pay that, but currently Best Buy has some awesome promotions on MBAs, which will suit me just fine. So I decided to go that route instead. So I say all of that to ask two questions: 1) Can I wipe my rMBP clean, or does it matter? It's password-protected, but I have my credit cards stored on the machine, and I would hate to have someone access that after they bought it. 2) How much do you guys think I could get for it? It's a mid-2013 rMBP with 256GB SSD and 8GB of RAM. It has very light scratches on the top of it, but besides that is in great condition. I appreciate everyone's input in advance!
