I want to buy a new MBP 15 mid 2015 from ebay. Its new, in the box, unopened. But what its strange is that you verify the SN on Apple website its appear to be already activated and under warranty only until may 2018. Why? Why its activated without being opened (as the seller stated)? Also can you tell me why Part Number looks like in the picture? It should be MLxx/xx... And why after 2.2/16gb/512 it appears DEU/DEU? Hope to get responses as soon as possible, because in a few hours ill meet the seller to buy it for 1300euros. what do you think, its a good deal? thanks a lot.
