I'm a bit confused about a recent ebay transaction. Someone bought something from me collection only, and the following day turned up at my house with the money. I hadn't received any contact from the buyer asking for my address, but did receive an email from ebay which was an automated response to a contact request from the buyer; but this only gave my mobile number, not my address.
It was fine, transaction smooth and friendly buyer, but I don't understand how they got my address? Is it sent automatically to buyers?
