Select varieties of 15-pack boxes of Luna Bars fall from $20.90 to $12.50 at Amazon. Add them to your cart with Subscribe & Save and they drop to $11.87 with free shipping - that's $0.79 per bar and the best shipped price by $8 we could find for a 15-pack. Flavors available at this price include Lemon Zest, best-selling Nutz Over Chocolate, and my personal favorite, S'mores. These bars are a product of CLIF Bar; they're 180 calories each and are made with 70% organic ingredients. You can cancel Subscribe & Save at any time and keep the discounted pricing and free shipping on your initial purchase; otherwise, you'll keep getting a regular shipment of this product.
