Years ago we used to spend more the we should have and thrown away way to much too, but now we shop wise, its very rare we throw anything away.
We could live on a lot less then that amount and we do, i am lucky the 2 kids buy there own junk food most days and only at the end of the money they may see whats in the fridge or freezer, they have even been known to open a can of beans and switch the toaster on, now thats amazing .
