On vacation my parents usually got us the variety pack of mini cereal boxes. You can buy mixed six packs of beers from many brewers. I ran into an issue this weekend when buying soda for my daughter's first birthday party this past weekend (by the way Happy Birthday Sylvia!). I knew lots of different people were coming, probably each had a preferred soda. I would be willing to pay extra for a 12 pack of say a mix of coke, diet, sprite, and orange soda. I guess I can only deduce that there are few people like me that want this mix of 12 pack of cans. Another possibility is that Coke and Pepsi have reached a good equilibrium where they both don't offer variety packs, causing people like me to buy too much soda. After all this thought I bought lemonade instead.
