Yes and Costco is the only retailer that puts their additive pkg. in at the station with each delivery. They have an automated system but when it doesn't work they have to do it by hand. One told me it is very thick and a pain to do.
With other retailers, it is done at the terminal. Costco doesn't trust the system, thus the reason for doing it themselves.
