Joining Costco - yay or nay?
I recently moved to the Boulder, CO area and am wondering if it makes sense to join Costco. Generally, I'm satisfied with the shops I patronize (Sprouts, WFM, TJs, Isabelle Farm, Atlas Valley) but am wondering if there are unique items or ones of particularly high quality (at good value) that make the membership, and trips to Costco, worthwhile. If you do recommend joining, specific recommendations would be most appreciated. Many thanks, my friends.
