I sold something on EBay earlier and when they came to collect it it wouldn't fit in their car. ( I had given them accurate measurements). I said that I would be able to take it to them tomorrow, for petrol costs. I ha looked up where the buyer lives and it would be a round trip of about 52 miles. Would a tenner be about right?
I know the cost will depend on the car size, traffic conditions, etc etc and I don't want to diddle her but equally I don't want to be out of pocket.
