I've just sold our crib on e-bay. It was clearly stated that it is collection only (buyer to pick-up) both in the listing info and description and our location was in the description. Buyer then announced they are too far away to collect it, and they will pay the postage, whatever it costs.
I've never tried to post such a heavy item, and even in bits it's still pretty large. Obviously it must be possible to post / courier it, but I'm not a mail-order company, and I really can't be bothered to schlep around getting appropriate packaging material and spending the time packaging it to ensure it arrives in its current condition.
I'd feel bad, but I'm sure I'm within my e-bay rights to refuse. What do you think?
