just remember that myfico.com is the only site to get your actual credit score from, and it will cost you about 10-15$ each score.
On the credit boards, i forget the name of it right now, usually post coupons for 20-30% off. Or try retailmenot.com they post some too.
If you're planning on doing a major purchase, i would pull your report, and once everything is clean... Any debts, any mistakes, that sort of stuff is taken care of, then pull your scores.
You're better off knowing what you're doing going into it. Rather than being blindsided.
For now, i just pull my reports. Once everything is cleaned up and gone, i'll check my scores. But i know that i can't get approved for anything, so it's low.
