I know this is an old thread, but I figured I would chime in.
Sams only had 11 lb briskets this weekend at 1.49 / lb - but I wanted a full packer. I tried Costco with a friend who had a card, and they only had 10 or 11 lb briskets - but at $2.49 / lb. And yeah, the butcher looked at me like I was from another planet when I asked him if he had a full 16 lb in cryovac...
Sams is closer to my home, but Costco is closer to my work. I was debating getting a Costco memmbership after my Sams one runs out - but now that I know they don't do bone-in butts or full packers I think I'll stick with Sam's.
Oh, and those "reduced for quick sale" meats are definitely a bargain when you find them.
I just wish they had a full packer when I went there on Thursday pm. I suppose I could have gone back friday durring the day and asked a butcher, but I was too busy looking other places.
