I would mention one very important caution

I would mention one very important caution – make sure no one has access to your credit card number.

I had a friend who cut up her card while she was paying it off but did not cancel it. She made payments for several months and when she finally looked to see what balance was still remaining, she discovered that someone had been using her credit card to make purchases over the phone to the tune of several hundred dollars.

So keep a VERY close eye on your number AND your balance.
