Amazon offers Prime members the Zippo Cedar Instant Campfire Starter 8-Pack for $10.13 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's the lowest total price we could find for this quantity by $11. (Most stores charge at least $2 per puck.) Each of the eight pucks is made of compressed cedar and wax and breaks into four pieces for a total of 32 fires.

Update: Price has dropped to $9.88.
