I was about to check my FICO scores, but MYFICO is offering the option of getting either Equifax or TransUnion, for $19.95.  Why not buy one, get one free, like grocery stores?    

If not, which is the better score to get; i.e., which one do creditors usually check?  I'd rather get both scores, but not at the current price for one.  Anyone know when the sale price for scores will be available?  I'm getting cheap in my later years.
