Stuffing the channel?

I went to the supermarket tonight, I have a friend visiting from California this weekend, and I wanted to make sure I had Diet Coke, the beverage of choice, in the fridge. Oddly, when I got to the supermarket, they were completely out of Diet Coke. However, they had tons and tons of Coke’s new C2 mid-carb beverage. It made me wonder if they were trying to boost sales of C2 by making it the only choice available to people who would normally drink Diet Coke.
