Amazon offers the Nestle Chocolate Assorted Minis 40-oz. Bag for $6.04. Check out via Subscribe & Save to cut that to $5.74 and bag free shipping. That's tied with yesterday's expired mention as the lowest total price we've seen. (It's also $4 less than you'd expect to pay in local stores.) It contains 100 miniature candy bars, including Butterfinger, Crunch, Baby Ruth, and Nestle Milk Chocolate.
Note: Be sure to cancel your subscription once your order ships to avoid being billed for further shipments.
