I've got several auctions running at the moment (standard auctions, no best offer option or BIN etc). Someone has just messaged me via eBay to say they're interested in buying five of the items I'm selling and has offered a price plus postage which I'm happy to accept. None of the items have bids yet and only one has a few watchers.
How do I arrange this so the transaction is still above board and through eBay? Is it possible?
