I have a plan I want to go into a phone shop tomorrow pre order multiple iphone 6 probably black 64gb most popular. Then I plan to put them on eBay on the 19th. In my experience people who haven't preordered are desperate to get their hands on one and pay crazy prices once they have sold out in stores. Is this a good idea, is there money to be made bearing in mind eBay fees? I don't know if: You can order more than one You can return them for a full cash refund If there will be a short supply If you are guaranteed to be able to pick it up on day one Any advice.
