I just bought 5 butts at Dominick's at Western and Roscoe last week as they were on sale for $.99/lb. I asked the manager behind the meat counter if they had any untrimmed in cryovac so he brought me out some. They come with 2 butts in each pack so I bought 2 packs, each weighed right around 15 lbs. Went back the next day and bought one more from the regular meat display that was 7lbs. I asked the manager about teh butss and he said they have plenty when they go on salke but generally they don't stock many because they are $2.49/lb.
Peoria Packing is great place to buy ribs, but their butts have never really impressed me by looks.
