I live in Los Angeles and I am looking for Avena Instantanea by Quaker. Does anyone know where to find it?

So far I have only been able to find it at Winn Dixie in Florida. However, that has been becoming more and more difficult. I prefer the plain and the vanilla flavors. The difference between Avena Instantanea and other Quaker oatmeals is that this one is pulverized.
