I have been a member of the Lexington Food Coop for over 30 years. I loved shopping at the Elmwood Avenue store because it's small, easy to navigate, and makes for a quick shopping trip. That said, they are building a huge new location on Hertel Avenue which will have a much wider selection of products and prepared foods.
You don't need to be a member to shop there, but it really pays to sign up. For a one time fee of $80 you get a lifetime membership. This entitles you to all sorts of biweekly member sales and discounts, as well as a yearly dividend, and the option to buy items you use frequently by the case at great savings.
The staff is just wonderful and make your shopping experience a true pleasure.
