Bag of Five Boon coins for the price of four coins.  Normally $5 each.
 
Each coin can be used in a variety of ways in our game and traded with other players and Storytellers.
 
"Boon" is an archaic word for "favor." Favors are the currency of the undead, and agreeing to do or owe a favor is a big deal among vampires. These favors come in varying degrees of seriousness from the trivial boon (hey, lend me your car for a night) to the dreaded blood boon (you owe me your life). The consequences for failing to perform or repay a favor you agree to can be severe, even fatal, and vampires who earn a reputation as boon-breakers can quickly find themselves without friends or allies.
