DO NOT SELL TO CEX. I recently took my 2012 MacBook Pro in to sell, which was in great condition with no scratches or dents, as well as functioning very well too. I took it to CEX and they gave me a quote of £250, assuring me that the laptop looked in good condition and so there should be no problem. I had wiped and reset the laptop, and so the worker was setting it up right in front of me, and it clearly was functioning well. They told me I would hear back from them within 2 working days max. After 6 days of absolutely no contact, I receive a call saying that I have to go and pick up the laptop as it "won't turn on". I was shocked by this as I knew for a fact the laptop worked fine. Upon arriving in the shop, I saw within seconds that the laptop had not even been charged! This was strange as I had handed it in fully charged. After leaving the laptop to charge for an hour, they said there was nothing they could do as they have been "trying to switch it on for days but nothing happened". What was particularly ridiculous was that they were in fact able to set up the laptop enough put a brand new password on it... I am greatly convinced that they took my laptop for parts and then claimed it was already broken when I gave it in, a clear lie. I wouldn't want this to happen to anyone else as now I can't even try to sell the laptop elsewhere as it is broken. Definitely use a more reliable shop or site!
