The cost for tires depends on the size and the mcg.
I did the 3 year alignment deal when I got new tires, where you pay once and can go back in to have your tires aligned whenever during that period. It was about $170. Not sure price on a single align, but they are very friendly over the phone. Bob usually works the counter/phone and is really knowledgable, so don't be afraid to give them a ring if you need more info.
Call them for a quote.
