Hi all, I've never bought eledtronics from Gumtree or Craigslist before but have used eBay in the past. I've have come across a good deal and I'm considering contacting the seller. Can someone give me some tips on what to look at for when buying an iPad from these sites, please. I'm inexperienced and don't want to get burnt. And advise would be greatly appreciated. Thanks in advance.
