They do sell different things at different stores, sometimes even within the same city. I have two Costcos within easy driving distance. One has herring and Kerrygold butter, the other does not. But the second one DOES have coconut oil and seaweed salad. Also, they are responsive to written(not email) letters. If you take the time to write a letter about something you would like to see at a store, they do their best.
