Typical supermarket price for St. Louis style ribs is around $4/lb (US$), about $9/Kilo. Local super market here has a sale on "country style" pork loin ribs for $2.88/lb. But you have to remember, I live where the pigs are (Iowa), so pork is very cheap here.
But, on the flipside, we get most of our lamb from Down Under/New Zealand, so you got us there.
