If you have a Safeway or Albertson's, Go there by Tuesday, spend $50 on other groceries and get a choice rib primal for $3.98/ lb. Got a 23 pounder that is marbled at the upper end of choice after picking through a few which were closer to select on the grading scale. Top round pricing, prime rib quality!
I submit, there is no substitute for prime rib, there is what you settle for instead...
