Having taught Business Math, I know a little about interest. CC companies love the uneducated or the stupid. Do you know that the average CC family carries a balance of $9,000+. Most of these cards carry a 21+% interest rate and if you pay the minimum amount each month it will take a person 23 years to pay off the $9,000. (Assuming you charge nothing else.) (Interest paid the first year on the card balance is about $1,900. almost enough to be making a car payment.) If you use a CC, wise up to the proper use of it. No private individuals receive that kind of interest on a savings account, cd's, checking accounts or investment accounts, at this time you are lucky to earn 5%.
