I love Sprouts stores, and they are my primary place to shop. This location is brand new and I've just started using it sometimes instead of the one on Deer Valley. I can't decide which location I like better, but they aren't hugely different.
The produce prices at Sprouts are MUCH lower than the mainstream stores. Sometimes by half. Other items vary, and there are some very expensive specialty products too, but the day to day staples are always well priced. Back to the produce, it's always very fresh, better than anywhere else overall. My wife loves their very limited and selective artichoke stock (only a few, only the best ones).
Customer service is exceptional. Everyone really seems to love the customers. Employees jump to help if you ask, and show you were things are instead of just pointing. They've gone in the back to get better produce when I grabbed the last item left and they saw it was a little wilted.
The selection of bulk products is excellent, and also well priced. They beat Costco on nut prices.
