PRIME strips 12.99/lb and Choice strips 9.99/lb at Costco. All the primes were gone when I shopped, but some of the CHOICE strips looked very marbled and at $9.99, I could not resist. Have to be careful and be picky to get uniform thickness, and good parts of the strips. Some of the offerings were not acceptable, i.e. small end pieces, uneven thickness, too much fat cap, etc. I got a nice pack of 4 (4.5lbs). Now vacuum sealed and aging in fridge. Each one will feed both of us as we both are limiting portions and I think 8+ oz each is enough for me. We both like the same doneness so I don't precut them before grilling. Bon Apatit!
