Smart and Final carries the red, some might carry the Gold.  Trader Joes also carries their yeast, but again I'm not sure if it's red or gold and it might only be in the little three packs.  You could check the Trader Joe's website, maybe. 

We have a gourmet cooking supply shop here called Surfas, I just checked there and they only carry the red.  Sorry. 

You can order it through King Arthur if they ship to you.

Sorry I can't be more helpful.
