Credit card is important for me. Credit card follows me every day because it sleeps in my wallet. When I buy some foods or commodities for home, I often pay by credit card so that I don't carry more cash to shopping. It is very convenient to me. Every month, I use my credit card to pay some bills on line. I don't go to bank or mail all bills.
