T&T Mart

T&T Mart 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 have greatly increased, however.

The selection of items offered are what follows:
 * Three pieces of furniture
 * Three tools
 * Two fortune cookies
 * Two wallpapers
 * Two carpets
 * One stationary
 * One wrapping paper
 * One medicine

The next upgrade is Super T&T, followed by T.I.Y., and finally, the T&T Emporium.
