1. Your top bidder never paid. Unfortunately for sellers, it is all too common for buyers to win an item and then decide they don’t want it after all. Making a second chance offer lets you offer the item to a buyer with a better reputation.
2. You have another one. If you have another item just like the one you just sold then you might as well sell it to another bidder – after all, you know they’re interested and what they’re willing to pay.3. A buyer emails you directly to ask. If they got ‘sniped’ at the last second, or just weren’t around when the auction ended, then a buyer might email you to ask if you’ll sell them one for however many dollars. You might as well make them an offer – it’s a free sale.
