I have a love hate relationship with BB.
My love is the surprise and the price. The concept forces me to become creative with what I get and try some items I might not have otherwise! The prices on the Alpine bread (sooo good!)
The hate? Quality is hit or miss. They have gotten better about it but it's still hit or miss. The fact that you're not getting quite the bargain it used to be. I am probably getting a tadbit more than I can get at Sprouts. So... not really a bargain anymore. Back to the Sprouts issue (which, by the way was founded in Arizona!), BB gets their produce from the same suppliers as grocery stores (Kodiak Produce), so do I support the Co-Op, which is volunteer ran, or do I buy from a grocery store and help somebody keep their job? I think the people are important, since Bountiful isn't local produce nor is direct from the farm...
I think I will participate from time to time (especially to stock up on the bread) but will stick with the Farmer's markets, Sprouts and Fry's and keep people employed.
