Why is Coke so Expensive?

Why does Coca-Cola sell for twice that of other soft drinks? It is made of the same ingredients, water, sugar and CO₂. The bottle costs the same. The bottling costs the same. The shipping costs the same. The difference is simply people have been talked into paying twice as much with advertising not because of any big difference in production cost. The difference goes to advertising and profit.
