Vanilla Coke and or the Zero Version?

I know that Coke is planning on rolling out Vanilla Coke Nationally again as of June 4th. I also know it is available in some US markets already. What markets is it already available. I am also wanting to know if anyone knows where in the Huntsville /Decatur alabama area that it can be purchased? I have checked the m retailers like Wal-Mart, and Target. I have also checked my local grocery stores such as Publix and Southern Family Market. Any idea of where I can find my old favorite soda?
