an 8 Charisma really is only "slightly below average." notwithstanding all of the formulas and percentages others have already used on this thread, think of it this way:
an 8 gives a -1 penalty. a 10 is a +0. there's no way to be more charismatic than this guy and still be below average. there's no penalty in the game between a -1 and a +0. therefore, his charisma is only slightly below average -- and it's the slightest it can be and still be negative.
as to Doc M's original point, i don't think he's being all that unfair to the character. (and i am, according to Robin Laws' book, a Buttkicker player. i don't mind accepting the social penalties when i make a combat character.) he's only apply this for major, unique purchases, and the guy does have some other circumstance penalties (being an outlander, refusing to abide by local customs in removing armor and weapons, and such). just remember that most bookish, solitary wizards are also going to have low Charismas and no social skills!
