if you click on the return item .. then instructions will follow..usually a print off label is produced...sometimes it's pre paid... if it has come from Amazon itself ..rather than a shop within you can take it to a collection point for uplift free... money is usually back in 21 days
spoke with nice Amazon person who gave me the address of the returns department so soon as i can will post it back to them, for a refund, as i said it for a considerable sum so that should come back into my account within 5-7 working days.
