Shops
Ammu-Nation, convenience stores, hospitals, and what you can buy.
Ammu-Nation
Ammu-Nation shops are marked on the map (Downtown, Cypress, Hawick, and more). Press E at the clerk to open the shop.
Typical stock includes pistols, a sawn-off (level gated), crowbar, parachute, ammo, medkits, and armor. Police officers cannot buy here. Use the armory on duty instead.
Convenience Stores
24/7, Rob's Liquor, and LTD Gasoline stores sell medkits and armor. Press E at the clerk, then set how many you want in the menu.
These same stores can be robbed by aiming at the clerk. See Store Robberies under Crime.
Hospitals
Hospital shops sit at places like Davis, Pillbox Hill, Rockford Hills, El Burro Heights, Sandy Shores, and Paleto Bay. The map blip uses the hospital name.
Talk to the doctor NPC (Press E) to buy supplies after a rough fight or respawn.
