There are places out there that will do a lifetime alignment for like $100-120. You get free lifetime full alignment for as long as you own the car. I recommend this because after 2-3 full alignments you will have cover the initial cost. Its best to get a full alignment twice a year or every 6 months. 
very true...get that if you have the extra cash....i think the requirment is every 6,000 miles or 6 months at a tire shop near me in atlanta...just like Elite said. And if ur really low on cash....just get the front aligned and see if it corrects the problem...then get the rear....you can also always ask an experienced tire man whats wrong with your car..that never hurts
also to add to what Elite said about your tires doing the turning. If you have a bad alignment....it will wear your tires more and more the WRONG way....even though your alignment might not be bad....it will APPEAR worse because your tires are getting eaten up....so..even if you get your car aligned perfectly..it might still go to the right or left until you get a new set of tires on there.
Hope that helps...
