Amazon offers the Lärabar Fruit and Nut Food 1.6-oz. Bar 16-Pack in Blueberry Muffin for $14.69. Add it to cart via Subscribe & Save and it drops to $13.96 with free shipping. That's the lowest total price we could find by $10, although in April we saw it for $5 less in a different flavor. These bars are gluten free, soy free, and dairy free.
Be sure to cancel Subscribe & Save once your order arrives to avoid being billed for subsequent shipments.
