tbobThese are the two most subjective grades in the hobby. I have seen F-G cards which most collectors would grade as around VG and F-G cards which you wouldn't line an animal's cage with. Ditto VG. I have purchased VG cards from dealers which are almost Excellent and VG cards which I would consider Fair at best.
My 2 cents is that if scans are not provided, try emailing and asking questions about creases/wrinkles/paper loss etc. although you always have to be careful about trimming issues.
I have learned the hard, hard way to always ask about paper loss if a back scan is not provided, even on "exmt" cards.
