Amazon offers the Clif Crunch Granola Bar 2-Bar Pouch 5-Pack in Chocolate Peanut Butter for $2.98. (Peanut Butter is available for a penny more.) Order via Subscribe & Save to cut the price to $2.83 and bag free shipping. Outside of the deals below, that's the lowest total price we could find by $6, although we saw them for a buck less last month. They feature no artificial flavors, colors, or preservatives.

Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.

Don't mind shopping in-store? Walmart and Target offer them for about the same.

Update: It's now out of stock at Amazon; however, Walmart still offers them for $2.98 plus in-store pickup, while Target charges pennies more via in-store pickup .
