the last one I bought was 16 pounds. I had to cut it in half when I loaded it into the smoker.
Many people don't know that Costco has two types of stores - the regular consumer Costco that everyone goes to, and they also have 17 specialty Costco Business Centers around the country. The Business Centers usually don't have the usual consumer stuff - computers, jewelry, clothing, optical, samples, etc., but are very well-stocked with things that restaurants and convenience stores need. The sell the 'primal' cuts of meat - those big chunks that you'd cut into your typical NY steaks or sirloins. Whole briskets, pork butts, untrimmed ribs, and 'special trim', which looks a little like flank but needs a long, slow, wet cooking to make it chewable...it's what Mexican restaurants buy to make shredded beef for tacos, etc. If you have the storage space and are willing to break down large quantities of food these places can be a great resource. We go to ours several times a year, in between our regular bi-weekly Costco trips.
Our freezer is well-stocked with uncooked as well as things that I've grilled or smoked and vacuum-packed into meal portion sizes, and I'll probably fire up the smoker in the next week or so and do another load of ribs and a pork butt for pulled pork.
Here's some background info on the Business Centers - and you can check the Costco web site to see if you are lucky enough to have one near you. (The one we go to is about a half hour drive beyond the 15 minutes to the regular Costco, but well worth the trip when we need to stock up - and they do have a lot of things that the regular store doesn't carry.)
