Timmy and Tommy's store

Timmy and Tommy's store is the main shop in every player's town in. It is located near the center of Main Street. The store is owned and operated by Timmy and Tommy, who replace Tom Nook's store from previous games in the series; Tom Nook now runs Nook's Homes, a real estate agency. In addition to buying items, the player may sell furniture, wallpaper, and fruit to the store for eighty percent of the value they would fetch at Re-Tail. Many of the store upgrades are similar to Tom Nook's upgrades, but the signs generally show two leaves instead of one to signify the dual ownership of the store.
