Michael has a credit limit and a balance of $3,000 on his Visa card- His car broke down, he charged the $500 repairs to his Visa which he knows put him over his credit limit for the month. His payment is due on the 20th so he made sure that he had his $750 payment to the post office on the 20th- Most likely, what penalties or fees, if any, will he incur?

Wise ways to use a Credit card are:
Pay off your balance every month. 
Use the card for needs, not wants.
Never skip a payment. 
Use the credit card as a budgeting tool. 
Use a rewards card.
Stay under 30% of your total credit limit.
