If it was like postage stamps, some people would buy a years supply now the price is going up!!
I think the number of people involving themselves in the Lottery has dropped and will drop further with the price increase. Anyway the Lottery was sold (I think) to a Canadian pension company so the funds are no longer controlled in any way by those who contribute or are UK residents and the proceeds certainly are not aimed at those who contribute. But this as always is the face of gambling.
