Imagine that your money is a little tight this month and you have two credit card bills to pay. One card is a Visa from a major bank; the other a card from a regional department store like Macy's. What should you do?

You should pay the regional department store credit card first since they usually charge much higher interest rates than banks and very expensive extra fees.

If you don't pay any of the credit cards your credit score will be affected, but you should always pay first the credit that charges the most interest.
