For me, Firestone laser aligned all 4 with a before/after printout and lifetime warranty for around $100. By "lifetime warranty" they mean I can bring it in as often as every 6 months to have another alignment done for free, even if needs to be totally redone after suspension work, etc. Seems like a good deal. The tech even did front camber. An autoparts store was sponsoring a grill in the parking lot so I just hungout eating free food and watched the entire job.
