My butcher carries them, but not cheap.
I also thought only Pacific Northwest costcos carried spiceology, I have not found it there.
Like most these days they do a nice Black Friday sale, and a few others sprinkled throughout the year.
I find them to be great quality and they have a ton of offerings outside the traditional BBQ rub guys.
I picked up an 8 spice sampler and we used and enjoyed them all. My family loves Greek Freak, Pink Lemon Peppercorn Thyme and Oh Canada so I ordered those in larger bottles and they were reasonably priced.
