I was just @ King Soopers the other day & they wanted $67 for a packer brisket. Forget the weight & per pound price but it was probably about 7lbs.
Not sure if there's a difference between Denver metro and Loveland, but KS near me still had flats for 5.99/lb and an untrimmed whole for 4.99/lb when I was there yesterday. I'm thinking of grabbing a flat and doing some homemade pastrami.
