Timmy and Tommy's store

Timmy and Tommy's store is the main shop in most of the player's town in and. In addition to buying items, the player may sell furniture, wallpaper, and fruit to the store. 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.

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. Items can be sold by the player for eighty percent of the value they would fetch at Re-Tail.

In, the player helps Timmy and Tommy build their store through donating materials and, in return, can place the store wherever they choose. Since it's the only place where the player's items can be sold, selling returns 100% of the resale value (except when selling through the drop-box, where the return value is decreased to 80% of its maximum).

Nookling Junction
Nookling Junction is the initial form of the store. It is similar to Nook's Cranny, the first form of the store in the prior installments of the.

T&T Mart
T&T Mart is the first upgrade of the store. It is quite similar to Nook 'n' Go, the second form of the store in the past games. The building's exterior has many of the same features as Nook 'n' Go's exterior, except it features an orange and white sign instead of a blue and white sign. This is the first upgrade with the catalog machine.

Super T&T
Super T&T is the second upgrade of the store. It is similar to Nookway, the third form of the store in the past games.

T.I.Y.
T.I.Y is the third upgrade of the store. Unlike the previous upgrades, it is very different compared to Nookington's, the last form of the store in the past games; it takes on the look of a home improvement store rather than a department store. The store is merged with the Garden Shop and has two separate entrances.

T&T Emporium
T&T Emporium is the fourth and last upgrade of the store. It has three stories: the Garden Shop and general supplies on the first floor, furniture, carpet, and wallpaper on the second floor, and GracieGrace on the third floor.

Upgrading
The requirements for upgrading are summarized on the table below.

Nook's Cranny
Nook's Cranny is the first store to open on the player's island. Initially, buying and selling is performed by talking to Tommy in the Resident Services tent. However, after paying off the first debt via Nook Miles, Timmy and Tommy will ask for the player to donate materials in order to build an outside store where more items can be sold.

"Hot Items" which are DIY items that sell for double their usual price, are selected at random each day. There is also a drop-off box, which players can use to sell goods without entering the store, even if it's closed. Items will sell for 80% of their usual sell price, and the total amount of Bells earned that day will be transferred to the player's ABD the morning after use, rather than given immediately.

The shop is open from 8 AM to 10 PM daily.

Nook's Cranny (General Store Upgrade)
After at least 30 days have elapsed and the player has spent roughly 70,000 Bells at Nook's Cranny, the store will expand. Unlike the previous games, the store retains the name "Nook's Cranny" after renovation. The upgrade is bigger in both size and selection and provides better tools. There are also now two Hot Items daily, rather than one.

So far, this is the only general store upgrade in the game.
