Amazon UK usually refund you as soon as the package is scanned into the shipper's tracking system. I've dropped off a return at a Hermes point and received a refund notification while walking back to my car. There is the caveat that they will recharge you if the item isn't in good condition, but if they never receive it, I guess they can only assume the shipper lost it.
