Costco Briskets
Costco has entire briskets for sale.
An untrimmed brisket is $2.99 a pound, while a Costco-trimmed brisket is $6.99 a pound.
Spending the 10-15 minutes trimming it myself (with a freshly-sharpened knife), resulted in an 8 pound trimmed brisket (4 pounds of fat cut off).
My roughly 12 pound brisket @ $2.99 a pound was ~$35.
A Costco-trimmed, 8 pound brisket, would cost $55.
Resulting cost of the self-trimmed brisket is $4.50 a pound.
