Costco Los Feliz
Wow...this thread is still alive.
Was at the Los Feliz Costco (about 6 miles south of the Burbank Costco) this afternoon and they had two prime packers in the area where they keep their prime cut meats.
What's crazy is that they were still $2.59/lb. while the choice flat in the main case was over $6/lb, IIRC.
