Like most things in life it pays to shop around. Up in this part of Canada we are lucky to find packer briskets PERIOD and when you do you should just quickly call 911 since someone's about to get sexually assaulted!! haha
That said, asking around and finding meat packers can save you a bundle. I love my local butcher but these things are special order items to them. I just can't bring myself to pay the near $7/lb for brisket. At that price I'll just buy steaks. What kills me is I drive by a Waygu cattle farm every week... wonder if they'd notice one missing.
