700 dollars seems to be way too high.
I know shops that will fix camber, caster, and heel-toe for $200 to $250 the correct way so you don't have to get a camber kit and worry that the ball joint will be knocked out of place someday. The alignment takes a long while though, usually over the course of a weekend if they have customers.
Any normal alignment for just the heel-toe is $40, but i'm no longer gonna get that since my camber and caster are all f*ed up due to an accident a year and a half ago. don't ask.
...and it's spelled "advice"... j/k
