I've got mixed feelings about this place. I love the fact that you can get almost any truly specialty/new agey/organic/yuppie product you can think of, but the cost adds up FAST! For me, Sprouts isn't a replacement for the "traditional" supermarket, it's more supplemental, as my budget can not justify some of the exorbitant cost of some of their products or lack of quantity for comparable priced items.
Though, the one thing Sprouts has that knocks the socks off of the "traditional" supermarkets is the very fresh produce department. Some of their fruits and veggies look so fresh, you'd swear it's wax props. Their staff also does an excellent job in making sure the produce section is continually stocked so you aren't sifting thru a dilapidated box of (name your produce).
Tip: Make sure before you shop here, you have a game plan ready, making a list and going through the sales ad for deals as it's easy to spend a couple hundred bucks for what feels like half of what you can get at a traditional supermarket. Be sure to also download the app and create a profile before getting to the store as the signup process is a bit tedious and will load helpful coupons within a couple of days.
