Pay Off Credit Card Balances Each Month For Free Money

Pay off the full balance of credit cards within the grace period and avoid finance interest charges completely. Now that's nearly free $$

Regular use of credit cards will improve your credit score over time. BUT, you should pay them off each month. Others would say, pay more than the minimum, and don't max them out. I say use them to your advantage and build credit scores.

There are credit cards that allow you to deposit money in them, say $500 or so, and that's all you can spend. These types of cards do report to credit bureaus, and you can improve your credit rating in this way.
