It would be interesting to see how much Coke with vanilla places like Sonic (http://www.sonicdrivein.com) sell. My partner always gets vanilla added in to his Coke when we eat there. Kroger supermarkets used to sell cans of vanilla cola in their store brand and I often bought that (I wonder if they still sell it).

I do love Dr. Pepper... As for Dr. Pepper being vanilla coke, I can see someone making the comparison - it is also kinda like a cream soda, another favorite of mine.
