If you get the lowest standard rate offered to new applicants you won't get your FICO score. Sure, Amex will sometimes offer people lower APRs than 17.24%, but that is the lowest standard offering to new applicants, so you won't get your FICO.
Oh well, I was looking forward to getting my Fico score for EX..... but I'll definately take the lower APR though.
Maybe I'll get it from my recent Freedom app, we will see.
Thank you all for the replies.
