T&T Mart

T&T Mart is the second expansion to Timmy and Tommy's store in, after being upgraded from Nookling Junction. The next upgrade is Super T&T, followed by T&T Home Center, and finally, the T&T Emporium.

T&T Mart looks similar to Nook 'N' Go found in previous Animal Crossing games, with similar glass windows, signage, and automatic doors. The store hours have increased, however.

To upgrade from Nookling Junction into T&T Mart, the following prerequisites must first be met:
 * 10,000 bell 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
 * 10 days have passed since T&T Mart opened
 * 10 days have passed since Garden Shop opened

Construction for the upgrades will take one day.
