This reminds me of my irrefutable logic that when something is half-price, you should always buy it. Eg if it was £20 and now reduced down to £10 . . .i If you don't buy it, you have saved yourself £10 and have nothing. If you DO buy it, you have saved yourself £10, and you have the thing as well.

Thanks for reading and joining in, Simon. I am indeed quite good at starting fires.
