the Integrity coupons you received in your (junk) mail contain some offers for 30/60/90k service. Price seems to be quite cheap. However you should call ahead to make sure all things that need to be done in your 30/60/90k service are covered using the coupon. Otherwise you would end up receiving a call when your car was in service, saying that X or Y are not in the deal and if you would pay for it extra so that your service is "complete" according to factory recommendation. The price of those "extras" (like an air filter not covered by the coupon) is kinda steep in my opinion though.
