Found a source since we don't have Restaurant Depot, just went to the Whole Foods Manager and asked him what he had. They were PRICEY that's my next job, find these, just not at their prices.
I'd say these were close to Prime (look at the photos).
I uploaded these with the new CS forum PhotoBucket:
7.5 lb, 3 ribs only. $5.99 a lb for what they call Chuck Short Ribs. Roughly 12 x 12 in size. I covered them with Worchestershire sauce and Montreal Steak. On the smoker now at 250. Took about 5 hours to complete, I pulled them at 200.
I never put them in foil, love the texture of these done this way. There is plenty of fat in these to keep them moist.
