I stopped at the Costco, in Carlsbad, on my way home again, just to verify the brisket prices.
Beef Brisket - Whole (Untrimmed) USDA Prime - Vacuum Packaged = $4.49lb
Beef Brisket - Flat (Untrimmed) USDA Choice - Vacuum Packaged = $6.69lb
Beef Brisket - Flat (Trimmed) USDA Choice - wrapped, on styro meat tray = $7.99lb
I didn't see the trimmed, Prime flat today. I was so tempted to take home a whole prime piece, but don't have the amount of free time, this weekend, to do it correctly. I don't want to freeze it either. One day real soon, though!
