T&T Mart (also known as convenience store) is a new store in Animal Crossing: New Leaf that is managed and owned by Timmy and Tommy. It is the second Nookling store in the game and the first upgrade, with the previous store being Nookling Junction and the next upgrade being Super T&T.
It is similar in appearance to Nook 'N' Go from previous games in the Animal Crossing series, sharing the typical convenience store design of a glass frontage and automatic doors upon entry. However, it has improved opening hours in comparison with the added assistance of changing the times through the Town Ordinance.
In addition to being a larger store, the Catalog machine will become available allowing the player to order items which they have obtained. The Gardening Store will also be available to build in the Town and will appear next door to the Nookling store. The Gardening Store must be built in order to upgrade.
To upgrade to T&T Mart, the player must have spent 10,000 Bells towards their House Mortgage and 12,000 Bells on items at Nookling Junction. The player must also wait for 10 days after the Town's creation before the option to upgrade is made available.
To upgrade the store to Super T&T, the player must spend a minimum of 25,000 Bells at the store and allowed 10 days to pass since the opening of the store, and 10 days of the opening of the Gardening Store.
