The last 4-5 years I have been saving all my change and I can say it works really well. The best tip I can give for saving is to get a wallet without a compartment for loose change. Thus, all change is put in my pocket and emptied when I come home. Whether it is a trip to store on the corner or coming home drunk from a night out, the change is put in my piggy bank..well actually a stubby cooler turned into a piggy bank :) I have been doing this for the last three years after coming back home to Norway. And it pays. Yesterday I went to the bank with all my change..a heavy load to carry I tell you. The teller didn’t stop until it displayed 23948 NOK. That’s $3785! I feel a vacation coming up :)
