I know Whole Foods has this combination sometimes, but I prefer to support local farmers, producers, and merchants whenever feasible. Thus, I would prefer to go elsewhere.
I know Fishhugger has grass fed, but it's impractical to go there to buy it. While I would consider buying in bulk, they do not offer a good value (who needs 50 pounds of ground beef?).
So, where's a good source for organic, grass-fed, free-range beef? It can be corn-finished, too... but, nothing out of a CAFO, thank you.
At the moment, I am vegetarian by default, being very skeptical about buying any other kind of meat. (Especially now that they have approved cloned meat for market)
