GTA 5 Cheats: Saving money with the Ammu-Nation discount
Things can get pretty expensive in Grand Theft Auto 5. While we've offered a few ways to earn a quick buck, another way is to simply save through discounts. Ammo can get pretty expensive, so one of the things you'll want to do is unlock the store discounts.
By completing all of the Gun Range challenges you'll receive a 15% discount at all Ammu-Nation stores. Getting gold rankings for all of the challenges will increase the discount to 25% total.
