This is an interesting question, as the final date is postmarked the Saturday following the quiz, ie 6 days later, then they must allow for postal delays, so I suspect that the draw is around the following Wednesday. I have won runners up prizes three times, but nothing for over two years, despite sending in more correct solutions. Some said that they spread the prizes around, and it you have won a couple of times, your name goes to the bottom of the list. I take this with a pinch of salt. It would be interesting to have a poll of just how many people have won prizes in the past twelve months. The puzzles vary, there do seem to have been more mistakes recently. I was not aware that there was an internet site!
