What I've done is ask the meat cutter person (regular grocery) to grab the grab the short plate still in the cryopac, before they cut it into 3-4" sections for the short ribs to set out in styro trays.....
Weigh the whole thing & tag it....if you're lucky they might discount the price per lb. 'cause there's less work involved....
just make sure ya got a big piece of charcoal to cook 'em up.....
