There is an interesting book by Adrian Slywotzky, The Art of Profitability, that goes over various profit models. I think the above example falls into 'Multi-Component' profit, in that the same product (water) is priced differently in different businesses (super market, convenience store, delivery); since customers behave differently in each purchasing situation you see the ability to price the product in various ways.

Another example would be how Coke is priced (to restaurants, grocery stores, vending machine).
