Costco Pepsi-iTunes Volume Availability Redux

From reader John Keahey,

"I work at a Sam's Club but the warehouse biz is pretty similar on all sides of the fence. BJ's, Sam's, Costco. We deal with the local Pepsi or Coke bottler to get the products we carry. It is entirely up to the bottler to decide what size to offer us. Our local Pepsi bottler sell us the 16.9 Oz bottles which are not part of the promotion. So not all Costcos or Sam's will have the promo bottles, and not all will have the same price."

This is also the problem with our local supermarkets which do not stock the 20 oz bottles.
