Not sure if many people know this but Experian offers a $0 free trial for their premium membership that gives a monthly refresh on all 3 bureau official FICO scores and even specialty scores like Auto Score 8.
So what i do is sign up, refresh the scores and cancel trial. Trial lasts 2 weeks so after it expires you can do it all over again. Ive been doing it for years and never had to pay a penny on credit reports.
