Today I took little drive out to where I know of a large and secluded Post Box. So all UK prizes to date are on their way to winners. That's Kathy K, April, Chris Smith and Jackie T. Posted First Class so they should be with you soon - many thanks to Sainsbury's, who will deliver stamps along with your groceries!
Still mulling over what to do about the Overseas prizes - there is a way of using Royal Mail on line to do the postage but my initial play wasn't too reassuring. It seems to be a very tedious process, so for now, my plan is to wait a while longer.
