The article I read said that the change would save Costco money, allowing them to keep the $1.50 pricing for the hot dog and soda drink. It also said that Costco polled customers, and found that something like 80% preferred Coke products at Costco food courts.
Both of these really surprise me. It is hard for me to understand that Coke can offer enough of a price savings, to make a difference in the $1.50 hot dog/soda pricing. I realize Coca-Cola is a massive company, that can afford to leverage their pricing, for the prestige of having their fountains in every Costco. But Pepsi-Cola is no small company.
I find it even more difficult to believe such a large share of Costco customers would prefer Coke. Admittedly, it has been a few years since I have read any articles about Coca-Cola vs Pepsi-Cola market share, but last time I did, I thought the split was closer to about 50% Coca-Cola vs 40% Pepsi-Cola, with the other 10% being other players. You would think, or at least I would think, that Costco members would closely mirror that brand preference.
