Item sold a while ago, buyer slow to pay - posted and it's now come back to me as not picked up in the 18 days I think you have to collect from the sorting office - messaged them to say , said I would refund but not postage.
They have still not contacted me - so it is ok to go ahead and do this and relist or do I need to cancel the order or something as I couldn't see an obvious answer on the eBay website
