In Animal Crossing: Wild World, Tom Nook stocks items based in Groups (A, B or C). The player's town is designated a group, and items from that group are more likely to stock in the store. Items from other groups will stock as well, but less frequently. The only way to find out what group the player's town has been designated is for them to keep a tally of the number of items from each group. Item Groups do not exist in Animal Crossing or Animal Crossing: City Folk, items are available based on individual towns. When the shop is about to upgrade, a message will be posted on the News Bulletin telling that on the next day, the shop will be closed for remodeling. Nook also sends the players a letter informing them that his shop will be closed that day.
Tom Nook's store made its first appearance outside of Japan in the Nintendo Gamecube Animal Crossing, as did many of the items sold at his store. The store was randomly located on the map of each town, but, like the Post Office, could only be found in the 'A' acres. The store offered furniture, clothing, tools, flowers, tree saplings, carpet, wallpaper, paint, and sign boards in exchange for Bells, the currency of the Animal Crossing world.
At the beginning of each game, the player will have a part-time job at Nook's Cranny, to help pay off their mortgage. This will involve making deliveries, writing letters, and meeting the residents of the town. While working for Nook, he gives a Uniform. This outfit is rare and it cannot be obtained from anywhere else.
After finishing the tutorial part-time work, the player is able to sell various items to Tom Nook in exchange for Bells. In many respects, these transactions form the core of the game experience.
Animal Crossing: Wild World
Wild World also featured Nook's store randomly placed, but as the acre system was discarded for this title, the store may be located anywhere in the town. Furthermore, it will always be accompanied by Mable and Sable's clothes shop directly to the east.
Several minor changes were made for this title. The sign board item is no longer offered, though other tools have been added. Nook also does not sell clothing in this title, except via catalogue; one must purchase shirts and other accessories next door from the Able Sisters.
Animal Crossing: City Folk
While the store is once again located randomly, it is no longer tied to the Able Sister's shop. Store hours for the Nook 'N' Go upgrade were changed, with the store now remaining open until 1am. Tom Nook's Point System was revised to include a gift exchange feature, so that points can be exchanged for rare items. The Shampoodle was moved from Nook's to the city in this title.
Interestingly, this title also features the thus-far unique ability to have Nook downgrade his store. Thirty days after the player obtains Nookington's, as they are exiting the store, Nook will ask if the player favors good hours, a balance, or variety. The player's response will cause him to downgrade to Nook 'n' Go, Nookway, or keep Nookington's, respectively. Any change, if requested, will happen a week later. If the store has been downgraded, Tom Nook will eventually survey the player again.
Animal Crossing: New Leaf
In Animal Crossing: New Leaf, Timmy or Tommy runs Tom Nook's old shop, as Tom Nook now runs Nook's Homes, no longer the shops. Tommy runs the shop on Monday, Wednesday, Friday, and Sunday. Timmy runs the shop on Tuesday, Thursday, and Saturday. Shampoodle's salon is not inside the shop in this title, but above Able Sisters. However, once the store gets its first upgrade into T&T Mart, Tommy will run the store in the morning and Timmy will work the night shift, similar to how Pelly and Phyllis run the Post Office. Tom Nook now runs a home improvement store called Nook's Homes.
These are the special features that Tom Nook's Store can provide.
The Turnip Stalk Market
A noteworthy item that Nook will buy is the turnip, an item that may be purchased by the player from Joan on Sunday mornings between 6am and noon. This particular transaction is notable because the price Nook will pay varies from day to day, forcing the player to follow the Stalk Market.
Aside from selling items in the store, Nook also gives the player access to their own personalized catalog, from which the player can order any item that they have held in their pockets. Anything that was ever held there will be featured, but rare items, fossils, fish, etc. cannot be ordered. When purchased, an item will arrive by mail in about five hours. Only five items may be ordered at a time between mailings.
In Animal Crossing, Nook offers a raffle for three rare items on the last day of every month. One entry for a chance to win requires five raffle tickets. Tickets are given to you by Nook during the month after the purchase of an item in the store (not for items ordered through your catalog). The tickets are only good for the month they are labeled for but can be used in the future if saved. Nook will only give out raffle tickets for purchasing certain items. Items that will give you a raffle ticket are clothes, umbrellas, furniture, wallpaper, and carpet. Nook takes your five raffle tickets, rolls the tumbler and lets out a colored ball. White balls are not winners. Green wins the third prize, red the second and gold wins the first prize.
Tom Nook Point System
When buying items in the store in Wild World and City Folk, Players are awarded Nook Points. For every 100 Bells spent, the Player earns 1 Nook Point. However, this is not cumulative: i.e. buying a pack of seeds at 80 Bells gives zero Nook Points, buying a second pack for a total of 160 Bells will still give zero Nook Points since they were purchased separately.
Nook Points serve to reward players for shopping at Nook's, offering discounts and prizes for their loyalty.
Methods for gaining points
The easiest method for accumulating points would be waiting for when Tom Nook has a "5 times Point Day". These days, which are announced on the town message board, any item will award five times the normal point value. A normal purchase of an item at 100 Bells will now give the player five points during these days. Items ordered from the catalog will work as well. During these times, a moon will give you 1,600 points and spending 400,000 Bells would unlock the Platinum membership. Normally, this amount would not be enough for Silver membership.
Nook's Cranny is the first incarnation of Tom Nook's Store. Open from 8 a.m. to 10 p.m., the player begins the game with this store.
In City Folk, Nook's store is laid out with shelving on the left wall, supporting one wallpaper (Changes daily), some flooring (Changes Daily), a flower seed or sapling, medicine, and some writing paper. Two pieces of furniture stand alone in front of the store. Three tools are set up on a table in the center of the room, which usually are a combination of Nets, Fishing Rods, Shovels, and Watering Cans. At the end of the shelving on the left is Nook's Point Tracking System. The bottom-right of the store resembles the cashier, and is one of the trademark features that all of Nook's Stores have.
'Nook's Cranny' is a parody of 'nook and cranny', meaning a small corner or hole. The store itself resembles a shed, made with wooden planks and held together with metal sheets. In fact, it is even stated that Tom Nook's shop may be Tortimer's old gardening shed before he became mayor. It is the only one of Nook's shops without an automatic door.
The player must spend and/or sell a total of 25,000 Bells and play for at least eight days for an upgrade.
After earning a Bronze membership at Nook's Point Tracking System, a model of Nook's Cranny is obtained.
Nook 'n' Go
Nook 'N' Go is the second of Tom Nook's shops in the Animal Crossing series . For Tom Nook to expand to this shop, the player will need to buy/sell 25,000 Bells worth of stock at Nook's Cranny and play the game for at least 8 days. It is the only shop that has a sign pole. This shop is also the one that is open latest, and earliest (From 7:00am – 11:00pm) (Animal Crossing) and from 7:00 am to 1:00 am in City Folk. In Wild World, the store opens and closes at the same time as the other stores. Nook 'N' Go also appears in Wild World and City Folk.
To upgrade to Nookway in Animal Crossing: City Folk, the player must buy/sell a total of 80,000 bells and the store must be Nook'n'go for at least fifteen days. To upgrade to Nookway in the other versions, the player must only buy/sell 65,000 bells worth of stock at Nook'n'go.
Nookway is the third expansion of Tom Nook's shop. For it to open, you need to spend 65,000 Bells at the previous Nook stores combined. It has a wider variety of items to choose from. This shop follows Nook 'N' Go. It is the second shop to have an automatic door. In Wild World, Nookway may or may not be the final shop for the player.
Nookington's is the largest expansion for Tom Nook's shop. In this expansion a whole new floor is opened up where furniture, wallpaper, and flooring is sold. Also, on the top floor Timmy and Tommy replace Tom Nook. In Wild World, after Tom Nook expands into Nookington's, the Shampoodle will also move into it to provide hairstyle makeovers for players at the cost of 3,000 bells. To get Tom Nook to expand into Nookington's, the player must spend 240,000 bells and have a friend shop at the store. This shop has an automatic door. In City Folk, you do not need a friend to shop at Nookway, and you only need to pay 150,000 bells for Nook to upgrade to Nookington's.
It is said that Nookington's closes earlier because of the fact that it could be Timmy and Tommy's bed time, thus there is nobody able to work upstairs, completely closing down the shop for the night. It is possible to see jewelry on the first floor, even though it cannot be found inside.
Upgrading in Wild World
To upgrade to Nookington's in Wild World, the player must spend 240,000 Bells at Nookway and a friend must buy something in the player's town as well. This creates problems for those who do not have a friend that they can connect with, and further problems if players do not have a sufficient internet connection using the built-in Wi-Fi using the DS (to connect to the internet) or Nintendo Wi-Fi USB Connector (that connects the DS or Wii to the internet using the computer) - they will be unable to upgrade. There is no other way to get Nookington's, though the problem can be solved by exchanging friend codes with another player over the internet. However, some Wild World game cards may have a glitch and will upgrade from Nookway to Nookington's whether a visitor shopped at the store or not. Online forums concerning the game will generally feature several people looking to travel and make new friends, with a dangerous risk.
