Amazon offers Prime members the Nature's Bakery Whole Wheat Fig Bar 12-Pack in Original Fig, Blueberry, or Raspberry for $5.84 with free shipping. (Non-members can spend $49 to qualify for free shipping; otherwise, shipping costs $7.69.) Outside of the deal below, that's the lowest total price we could find by $6, although we saw them for a buck less in another flavor in August. These bars are soy-, dairy, and cholesterol-free and are vegan and kosher.
Of note, Walmart offers two 6-packs for the same price via pickup.
Update: Blueberry is now part of Amazon's "Add-on program," so it's best to opt for Subscribe & Save to get it for $5.55 with free shipping. Be sure to cancel Subscribe & Save once your order ships to avoid being billed for subsequent shipments.
