How many COSTCO Pizzas to justify membership (vs Dominoes)

how many Costco pizzas do you need to buy every year to justify your $60 annual membership so in this video I explained why Costco was a better value Pizza compared to Domino's and I've been getting several comments saying that you didn't take into account the cost of the membership valid point let's talk about it so at Costco you can get an 18in pizza for $10 whereas in dominoes the largest size you can get is a 16 in and it costs $21 and if we adjust this to the same size as Costco it would cost $265 meaning each time you buy a Costco you are saving $16.57 and if we divide that into the $60 annual membership fee we would find that you need to buy at least four Costco pizzas every year to break even meaning every Pizza you buy after the fourth one is going to be pure savings and let's be real for 99% of you buying four pizzas in a year is easy
