Some places are less forthcoming with what their bulks are. The Gatlinburlier in Gatlinburg, TN, was telling me a whole hoopla of stories about how the blend was specially grown just for them, just down the road off the Blue Ridge Parkway, yaddi yaddi ya... I pointed out that Peter Stokkebye was one of my favorite blenders, and that each of their blends came straight from the PS catalog without any changes. I even went through the whole selection and pointed out what each one was called. He finally hung his head and winked, but then kept telling his stories to the rest of the suckers in the store.
I'm not sure why they would do this, unless it was to make themselves seem more important than they are. Why not just have a blend really special made for the store? I know that The Briary is working with some companies on getting some of his own blends made. McCrannies does this also. It does require having huge minimums made up, which is a dent in the budget, but I would think that the rewards of having a store blends actually tinned up for these places would drive in more business. Heck, I send McCrannies a check a month to keep the RR coming in the mail. And, I wouldn't even have known who they were except for this blend.
