Main reason that I buy most of my bbq cuts at CostCo is that they aren't "enhanced." My local butcher's stuff is excellent, but a tad pricey, so I tend to reserve buying from him for special cooks. And I see absolutely nothing wrong with wanting to use the best grade of meat that you can get your hands on?? I buy prime brisket when the price is right at CostCo. Don't think that makes me a "hipster" at all - because I patently refuse to wear white socks with sandals - LOL!!
Have read Mixon's book and he's always been totally unapologetic about being a douche bag, even before the TV exposure, but when you got the hardware to back it up. For the rest of us, there's Steven Raichlen and Chris Lilly (and countless other "nice people" in the BBQ world, like on this Forum!)
