I’m planning on getting a new MacBook and trading in my old one. It has a brand skin on it and honestly I do not want to take it off before i know exactly how much they will give me in store for it. The amount they quoted online is sufficient however I do not want any surprises and if there were to be I wouldn’t want to have the skin off and not end up doing the deal. Anyone ever traded one in that had the skin on it? Do they make you take it off? Do they keep it on and take it anyway? Thanks.
