The Receipt is an item Harry Mason picks up in Silent Hill. Harry can find the receipt, along with Kaufmann's motel room key inside Annie's Bar. After saving Michael Kaufmann from an attacking monster, he and Harry will have a short conversation before Kaufmann hurriedly leaves. After he is gone, Harry can pick up the receipt and a key on the ground between the pool tables, seemingly dropped and forgotten by Kaufmann.
The receipt has a four-number code (0473) written on it that can be used to open the door to the Indian Runner general store, the next destination in the Kaufmann Sidequest. The number remains constant for every game, however the sidequest cannot be completed without picking up the key and the receipt.
