An invitation is a unique piece of stationary that cannot be purchased. It only appears in Animal Crossing: City Folk, and is used to gain access to Crazy Redd's, located in the city. A villager may ask the player if they wish to become a member of Redd's store. If they accept, the villager will mail the player an invitation, which will arrive in their mailbox the next day. After this is obtained, players can enter Crazy Redd's. A membership fee of 3,000 Bells is required before purchasing any items. This event occurs only after the player unsuccessfully attempts to enter Crazy Redd's in the city.
