With the exchange rate that equates to $100 australian, id like to do eight alignments a day, whoo,oo id be rich. Seriously, all front end work carried out alter previous settings, especially if you mix the camber/caster shims. pulling usually indicates less caster on the side it pulls to, the near side always should have .25 to .75 degrees more than offside to counteract for road camber. Also if you swapped wheels over they can pull also. swap fronts over to see if the pull goes the other way, if there is no difference that rules tyres out.That sort of money should buy you a comprehensive alignment so make sure the guy gives good value.
