I went for almost 20 years without carrying cash at all and just use my credit card for everything. Pay it off at the end of the month. It’s fantastic. The extra money I got at the end of the year from my two credit cards was actually kind of shocking. Although one of them gives me airline miles instead of money.
I have been using my credit card with cash back of gasoline, and major purchases. When I need appliances I apply for a new Lowe’s card and get 20% off same day. I have started to use my credit card for things like pizza and Dunkin. The dry cleaner is a nice guy and I don’t want to squeeze him for the vig on the credit card, which is the main reason I do not use credit cards. Other than that, just about everything is credit card today.
