I pay $2.79/lb at Costco for PRIME whole packer brisket (approx 14+ lbs flat and point). Costco, Sam's, Restaurant Depot. Any of those stores in your area? Membership dues could be worth it for the meat savings and availability alone. Otherwise, your $7+ prices are probably in line with butcher shops and meat markets. Shoulder clod might also be good, but it's huge, so don't know if you can get a 1/2 clod. I'd bite the bullet and pay what you need to, to get the best brisket for Christmas (if you need it for Christmas dinner). Then make it your mission after Christmas to seek out alternative sources.
