We just got a membership to Costco. I haven't bought a pork butt there yet but I looked at their meat on our maiden voyage. Right now I get my pork (ribs and butts) at Hy Vee and they're Hormell. I noticed Costco carries Smithfield (I think, I'm not 100% positive). Their ribs look fine, they come two to a pack, which I can deal with. But I noticed the pork butts are HUGE. Hy Vee sells avg. 3lb boneless and avg. 6-7lb bone-in. These Costco things were like 17lbs. Is this two shoulders packed together or what's the deal?
