This Pizza Sauce is what they use in the food court at every Costco. It is only sold to Costco members at the Costco Business Centers. However, the same sauce used by the Costco Food Courts is not the concentrated version. (less work for the employees and exact each time) The Costco Business Centers used to sell both types of the sauce, but now just the concentrated sauce which requires water added. The boxes contain these plastic pouches filled with sauce.
