I begrudge buying toilet paper! As we live in a house with a septic tank - the cheaper and nastier the loo roll the better, though you have to find a happy medium as you don't want any nasty "wiping injuries"
Talking of them - when I was a kid we had Izal toilet paper and if you didn't fold it right you could render yourself unable to have kids! No wonder the boys sprinkled when they tinkled!!
