Where to Get Cheap Carfax Reports?

I’m a new dealer in PA, and I’m quickly realizing how expensive Carfax reports are—$45 for one report adds up fast. I know some dealers get unlimited Carfax accounts or buy reports in bulk for way less. I’ve also heard that some people rent out dealer accounts to pull reports, but I’m not sure how that works.

Does anyone know the cheapest way to get Carfax reports or if there’s a cheap Carfax alternative that’s actually reliable? Just trying to keep costs down while running history checks on cars. What’s everyone using these days?
