For a grocery store offering, boulder sausage is a good one.
I suggest you call clyde's down in denver, ask for Mike. Or leave a massage to order some of the chorizo they make. While you're at it, definitely grab a few 4-packs of the cured hot italian sausage.

3655 Inca St, Denver, CO 80211 worth the drive. One of the few food places we miss in CO. You can always call in an order the day before. You can order the sausage in link, coil, or bulk. Or you use to be able to. Who knows how they're operating with this virus. Try the sweet italian sausage, too.
