[Costco] HOT! St. Louis cut side ribs $15 off/pack, all Canadian locations

Was in the Kitchener Costco today and saw this as an in-store special. St. Louis cut ribs on sale for $15 off per pack. Each pack is two full rib racks, price for each before discount is in the $24-$32 range. I grabbed 4 packs, each of which ran between $10-$15 after discount. This is a great deal on the best cut of ribs, there is nothing to throw away, no keel or inedible end bits. People were grabbing 2-3 each, but they appeared to have lots.

*EDIT* Appears this offer is at all locations.
