You might want to reconsider your approach to those amazon boxes... 1) Amazon puts 'Prime' labelling on all their parcels, not just ones shipped to Prime members 2) People use Amazon as a way to send people gifts! If I know your address, I could order you something I think you might like from Amazon. They'll even giftwrap it and put in a thoughtful note from me! You don't need an account for that to happen. 3) Because of the ubiquity of Amazon, the world is full of reused Amazon Prime labelled boxes. Maybe your ebay seller is shipping you something in a previously-bought-from-Amazon box.
