I think that's a fantastic idea, so simple and yet as you say, it's surprising how quickly it adds up. I always wonder when I see change on the side where that will go and how it'll be wasted.

As a child, my parents made me fill a smarties tube with 20ps - it makes £15!!

I really feel for you!! I am sending you so much luck and best wishes (I'm currently two people so it's doube luck.. hehe).

Lots of luck xoxoxoxo
