T&T Mart

T&T Mart (コンビニまめつぶ) is the second expansion to Timmy and Tommy's store in, after being upgraded from Nookling Junction. The upgrade brings increased store hours, a greater selection of items, and the catalog machine, which can be used to order previously held items.

T&T Mart looks similar to Nook 'N' Go in previous Animal Crossing games, with similar glass windows, signage, and automatic doors. The store hours are later or earlier than previous games if the Early Bird or Night Owl ordinance is in effect.

Selection
The selection of items offered are what follows:
 * Three pieces of furniture
 * Three tools
 * Two fortune cookies
 * One wallpaper
 * One carpet
 * One stationery
 * One wrapping paper
 * One medicine

Upgrading
To upgrade from Nookling Junction into T&T Mart, the following prerequisites must first be met:
 * 10,000 Bells home deposit paid to Tom Nook
 * 12,000 Bells spent at Nookling Junction
 * 10 days have passed since town creation

To upgrade T&T Mart into Super T&T, the following prerequisites must first be met:
 * 25,000 Bells spent at T&T Mart

Construction for the upgrades takes one day. Upgrading to T&T Mart will trigger Dr. Shrunk's appearance at the player's house to determine if Club LOL will be constructed on Main Street.
