Most medical offices or places set up by the state or medical are free when you have a valid reason. Testing to get a negative to travel or otherwise could cost you. Also some clinics and offices will test you for strep at the same time which also could ding you or your insurance. We have a couple of local pharmacies doing the tests for any reason without question that charge as they aren't set up to bill insurance and aren't getting state or federal funding. Those ones charge and have been about 50 bucks
