Well the best way to saving money is the invest right place to more profit or income you can get and save money.
Cut up your eftpos card, it forces you to go to the bank to get money out. When you have had a few beers and are not thinking as clearly as you normally do the bank will be closed and you can't waste to much money. Unless your an alcoholic and start drinking at a crazy time. Damn I want a beer. Damnnnnnnnnnnnnnnnnnnnn
