I just bought a new in box never opened MBP on eBay. once it arrives I should be able to register it with apple and all will be fine for the battery exchange etc? this will not effect the warranty or anything? thanks for the help, this is the first major item I've ever bought on eBay but I got this guy for only $1500 & the seller has a 200+ rating so I feel I got a pretty good deal. and I should be able to apply the apple care right away?
