i save my change and my bills b/c it has cut down on my spending. i wind up saving approximately 25-30% of my monthly allowance by saving change and bills, whereas before is pent it b/c it was 'fun money' allocated to be spent.
and to be honest, it saves me a little bit of time and frustration, too. no more looking for change in the car at the drive through, no more digging through my purse looking for a penny at the grocery check-out. just hand the person a $5 or higher and get on with it!
