I sold some furniture on EBay and stupidly offered to deliver it as I was going to be close by. Now I realize the thing doesn't fit in my car - I had measured it, but it's a funny shape and I didn't realize how awkward it was. When I had made the offer dh said it might not fit, so I did message and say I would need to check if fitted. So - it doesn't. I have messaged to apologise, asking the buyer to make arrangements to collect. No response ( only messaged today, so there is time). Are they still obliged to go through with it? I might be worrying over nothing, the offer to deliver was made after the auction had finished.
