I'm fairly new to eBay selling, so not sure what I'm doing with this one. I listed an item and despite unticking the option to accept Best Offers, it went on with it anyway (seems to happen quite a lot!). I didn't bother to edit it and received an offer, to which I made a counter offer. eBay said they would notify me when the buyer responded. No notifications came through, but about 12 hours later the item sold at the full BIN price. I happened to be on eBay when this happened and saw that "payment information" was being requested. Once I looked at this, I realised the buyer was the person to whom I'd made a counter offer. However before I could edit any payment information, they paid in full at the listed BIN price.
Is it normal with accepting Best Offers that you will need to manually edit the payment information? In this case do I now need to refund her the difference between the offer I'd made and the price she paid? It's a low value item, so we're talking a very small amount of money, but I'm just not sure what I should have done, or how I should proceed now.
Thank you!
