Northern grocers are horrifying. Don't need a study to tell me that. Food handling and storage rules? If they are convenient, or if they get a heads up that the inspector is coming (and they get a big heads up on that, because the inspectors need somewhere to stay, plus they probably hit everyone else up on the way). If the item you are after is anything popular or in demand, it's 2x-4x the price anywhere else is paying.
