What should I do with the change in my change-jar?
Every now and then I fill a pocket with a handful of coins and spend it on a very small shop on my way home, i.e. a loaf of bread (£1.50), a pint of milk (50p) by using the self-check out (Tesco/Sainsbury's) which has a coin slot or even better the little bowl where you put coins down. I find this pretty straightforward. There's no point having a jar at home worth £50.
