Amazon offers the Cheez-It Crackers 1.5-oz. Bag 36-Pack for $8.63. Checkout via Subscribe & Save to drop it to $8.20. With free shipping, that's $10 less than the best price we could find for a 45-pack elsewhere and the lowest total price we could find, although we saw it for a buck less in January.
Note: Be sure to cancel Subscribe & Save after your item ships to avoid being billed for future shipments.
