I bid on a coat which wasn't made of of the fabric it was described as - seller made a mistake on the listing. Although he said he doesn't offer refunds I emailed him and he now says he will refund but he will not pay my return postage, leaving me out of pocket by a fiver!
Under these circumstances does the seller have to refund return postage- it's not that I've changed my mind or whatever, just that I would never have bid if it had been described correctly
