I'm not a meatcutter, but I love hearing about the business. I love meat.
Around me most stores sell beef ribs for around $5/lb, some as high as $8. One store always has a bunch, and usually asks $2/lb, and often has some marked down to 99¢.
I have recently discovered sous vide cooking (I made a controller very inexpensively) and beef ribs are great cooked that way. I often cook them for two or three days at very low temperature. The tough stuff just melts away, but I only let them cook to medium rare. Then I pull them out and sear them to give it a nice crust. Its amazing...
Bone in or boneless back ribs (have not seen these outside the commissary) under $2 pound. Bone in short rib $6.50 pound. Boneless short rib $3.80 pound. Goes up and down a little in price.
