Tombstone is running their usually Trick or Treat Halloween promotion on their Facebook page. You like them, then knock on their door where you will be presented with a coupon.
You can either get $1/1 Tombstone pizza, $.75/1 Tombstone pizza or $1/2 Wonka or Nestle fun size candy. the promo only runs until 10/31. The coupons have 30 days till expiration from the date of print.
It states limit 1 coupon per week, but I was able to knock 3 times and get all 3 different coupons. :)
