I'm new to selling on eBay, so I'm not sure what the protocol is in this situation. I'm selling a book on auction for £4.99 which ends in 2 days. A potential buyer has just messaged me asking if I will accept £3 for the item if I end the listing now. It is quite a niche book and it has only had 3 views so far! So I'm thinking this is my only chance. However, the potential buyer is also 'watching' the item, so do I just let the auction run its course and hope he bids? The other thing is, I've no idea how to end a listing or what the payment procedures are if I do go ahead with the offer from the buyer. Any advice?
