I’ll be looking to sell my iPad Pro in a couple of months. I don’t think I want to ride the eBay roller coaster. I want to arrange a meet and do a handover for cash. I see a lot of people from the States recommending particular websites that are good for this, but none of these exist in the U.K. What are the best sites to use in the U.K.? Pretty much the only one of a decent size that I know of is Gumtree, but even the market there seems pretty small.
