I’m not sure what’s happened with Best Offers, but I was under the impression that the highest price that could be offered was the asking price. This obviously isn’t the case as I’ve just had an offer (which I accepted) for £15 on an item with a price of £14.99.
I’ve asked around and other sellers have received and accepted similar offers higher than the listed price. In my case it was only a penny higher but apparently offers significantly higher than the listed price have been made and accepted. It may be a bug or it may be intentional, but I’m still amazed that a buyer would be willing to pay more than I thought the item was worth.
Have you received any offers higher than the price you listed the item at?
