Binco is not based on any specific real-life store, though it may be either a thrift store or clothing exchange store like Plato's Closet. This could possibly explain the signs in the store which read "Everything 99¢", however nothing the player can buy is 99¢.
The store's motto is, fittingly, More trash for less cash!.
Clothing
The range of clothing offered at Binco are generally affordable, with prices that do not exceed the $100 mark. The store's selection of items are centered around generic clothing, as well as low-end clothing commonly donned by gang members.
The store also offers various novelty articles of clothing, such as joke eyepieces, masks, and a cowboy hat and cowboy boots. Binco also earns the distinction of being the only store chain to sell briefs (known as Boxers in-game, which can only be worn without pants) to the player.
The default clothing for GTA San Andreas protagonist Carl Johnson is entirely derived from Binco's range of items, including the White Tank (Torso), Blue Jeans (Legs) and Black Low-Tops (Shoes).
In Grand Theft Auto IV, the Russian clothing shop is implied to be initially designed as a Binco outlet during development but was changed for unknown reasons. If Niko walks into Modo wearing certain outfits from other stores/sources, the sales assistant will ask if he has been in "a Binco explosion".
