re: How often do you go a day without spending any money?

Yeah, I'd say we are able to do it once or twice a week. We try to go to the grocery every Sunday to buy what we need for the week, so unless I need to stop and get gas on the way to work, we shouldnt have too many daily expenses. Wife stays at home with 2 kids.

Easy for me, too. Packed lunch most days, make an iced coffee at home for the drive to work. Free coffee at work. We generally shop in bulk once a month or so, with a produce or farmer's market run once a week. Easy for me to go a week without spending...my most frequent purchase is probably fuel.
