Why use cash? I use a card that gives me 1.5% back and pay it off weekly.

I get back hundreds.

[Tell It Right]

The idea being that using a card is hard for some people to realize how much money they're spending (a swipe here, a swipe there). But spending cash makes people see money leaving their hands and is more liable to make them realize they're spending money.

I'm with you. My wife and I use a credit card for random regular spending. We never go past our weekly budget for it. And I pay it off weekly. In the course of a year we get back about $500 to $600.

Of course, that's not enough of a reward to offset bad spending habits if a credit card increases spending. So it should be a person by person decision.
