Convenience.

It matters more with the soda- nearly all the 20oz. bottles sold in grocery stores are already cold, making them immediately drinkable. Warm soda is *icky.*

The chips, too- it's more convenient to buy a small bag and throw it away than to buy a larger bag and have to find somewhere to keep it until your next snack attack.

Consider that most people are buying this stuff for their lunch at work or something, and it makes much more sense.
