FYI Watch out for the "free" credit report offers such as freecredit report.com and whatsmycreditscore.com that are regularly advertised on the television commercials.
We had cancelled ours only after a month and they somehow manged to deduct a small amount of money once a month out of our debit/checking account the following months until we caught it and contacted our bank.
Please be sure to check your monthly/quarterly statements folks! If all of a sudden you are bouncing your check balance for no reason-- well this may be the reason!
You would think that by the ads they are there to help you, not to help themselves to what is in your bank account! Be careful.
