What should I do with the change in my change-jar?
Are you in an occupation that regularly collects change or is this change left in your pocket at the end of the day? Here in the US it is typically worth it to invest in some automatic coin counters if you are in an occupation that regularly collects coins.  In your case you can collect the little baggies from the bank, use your coin counters and then make a deposit.  Here is an example of US coin counters. If it is just pocket change then in the morning, make it a habit of taking some with you.  This way you are less likely to break larger bills.  Also if you are making a deposit at the bank, add some change to the deposit without making it to annoying.
