Amazon offers the Kind Gluten-Free Bar 12-Pack in Fruit & Nut Delight for $10.59. Checkout via Subscribe & Save to cut that to $10.06 and bag free shipping. (Target charges the same price.) That's about $6 less than you'd expect to pay in your local store, although we saw them for a buck less last September.
Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
