So the battery of my MBP 13inch retina is failing, I got it from eBay. Apple quoted a repair charge of $199, does anyone know the repair cost at Best Buy (Geek Squad)? Any ideas on how to get this repaired in an economical way? iFixit has a kit but I'm not sure if its safe to do it at home though. Can I get a squaretrade warranty for it and get it fixed through them?
