Can I get wheel alignment and tire rotation done even if I've not purchased tires here? If so how much does it cost?

I bought 4 tires here late last year. I took my car to Firestone to get a 4 wheel alignment on lifetime policy. Costco will rotate and rebalance wheels every 5,000 miles for free. I don't think they offer alignment. Not sure if they will work on a cars' wheels if you didn't buy from them. They're usually very busy all day every day.

They only sell tires and install. They won't rotate tires.

I think so. Not sure on the cost. Have to be a member
