As you probably know you can set a price where Ebay will automatically accept best offers of this amount or more to speed up the selling process. However, why do Ebay not demand immediate payment if the best offer is auto-accepted at the time of submission like they would with a normal 'buy it now'? It's infuriating that I supposedly sold an item this morning, seven hours ago, and the seller still hasn't paid despite their offer being accepted there and then. What possible reason could there be for a delay in payment? They saw the item, liked it, made an offer £19 less than my buy it now price and it was accepted immediately. They then disappeared without paying.
