Couple Costco gas have air pumps but not where you get gas, off to the side by the curb most likely or at the tire service center.
No not at pumps but in front near tire department.
Not at the pumps, you need to go to the tire center. It's on the right side of the store facing the toll road's dirt bank. If you're not familiar with the process just look helpless and someone will come out to assist you.
Yes at the tire service area
Tire center
