Not sure about Music Magpie. Sold an iphone to them, no issues whatsoever. However, sent in a Macbook Pro (fully working) as offered £400 but was told within 30 mins of them receiving the mac that it was faulty (apparent hardware fault) and they offered £80 instead. Now I know that the mac was working perfectly and so declined the paltry offer and the mac was sent back. I have checked the mac using Apple Diagnostics and no errors whatsoever! Not sure what they are playing at but thought potential sellers should know. I may be less sceptical if they provided full details of the so called fault so that I could confirm the issue but nothing was forthcoming.
