69¢ Store
The 69¢ Store is a 24-7 discount store that has two locations in Los Santos, one in Idlewood (not accessible), and another in El Corona which is accessible to the player. These stores are based on real-life 99¢ stores, and another one of the many references to the "69" sexual position made throughout the game.
They can be faintly seen in the GTA IV Era however they are inaccessible to the player.
