I am working on spring cleaning the house, but I also thought that I needed to do some other cleaning too. I haven't checked my credit score in a number of years - bad I know! So yesterday I signed up for my free credit score at myFICO's website. It took only minutes to setup my profile and get my score. You can have a free ten day trial of their product and then if you still want it you can purchase it. It is very easy to cancel and didn't take long at all to do.
There are a number of other credit check websites that you can use as well...all that matters is that you make sure you check your score periodically.
