Credit Cards and Impluse Buying

Do credit cards increase the need for an impulse buy? Many of our citizens in the U.S. today have credit cards. It's a likely chance that the chance of impulse buying occurs more often with those who have credit cards. When people know that they can buy a product just because they can swipe a card, they are more likely to do so than an individual who has just cash and can't afford such a product at a price beyond what he/she can spend. People with credit cards are more likely to be in debt as well than others who don't have them. Do you believe that impulse buying occurs more with those individuals that have credit cards who spend more than what they have?
