I’ve listed something on eBay, auction only, for a starting bid of just over £100. Someone’s messaged asking if I would pay the postage (within the UK). They haven’t bid on it yet but postage is listed as £3. It just seems odd to me that someone would spend over £100 then quibble over £3 postage. It feels off but I can’t work out how it could possibly be a scam. What do you think?
