Too bl**dy much. And have you tried that disgusting Vanilla Coke? Yecch! I love vanilla, but ... why?? Diet Coke with Lemon, now that's a different story. Virtually no calories, and tastes great. What more could you want?
No idea, I'm afraid, but I can strongly recommend For God, Country and Coca-Cola: The History of the World's Most Popular Soft Drink by Mark Pendergrast -- a very readable history of the drink, the company, the brand, the world domination. It discusses the kind of moneey they have churned over *and* publishes the Top Secret recipe for the very first time.
