I have been to Earthfare a few times and think, like every other grocery store they serve a specific purpose. For the things that they stock and have priced competitively, like a certain Gluten Free baking mix that is priced equal to or better than we can find elsewhere they're good. I like walking through the store and checking out what they have, but if you're a savy shopper you wind up thinking "Darn, I can find "item X" cheaper online, at Harris Teeter, Whole Foods etc..."
Service wise, I have encountered mixed results both good and bad. Ultimately the purpose of every good grocery store is to get people in once and have the stuff they need to buy all in one place to eliminate them going to multiple ones. Earthfare definitely does not accomplish this and mainly it's because of their prices. In the meantime I will go in there, as usual with eagle eyes to bu my one or two items and ride down the road to Harris Teeter for the rest.
