This is my favorite money saving method! I put all my change in here and extra things like GST cheques or autopac rebates and usually have enough for a trip once a year.
I think that it is a good account the one minus that I see with it is the $5 fee to withdrawl from an ATM: but this is also a great deterant to save my money. When I do need it I can do a free online transfer.
