I have been selling off some collectables and often end up with international buyers. My settings are UK only so they send things to companies based in the UK who forward them on. I was wary but have never had a problem so don't mind. I have just sold £100 worth of items to such a bidder (who also has zero feedback) who is now asking if I know of a cheaper service to the one they have selected (so a change of address). Is this dodgy? It doesn't feel right.
