To get Coupons quickly in Stalker 2: Heart of Chernobyl, follow these detailed steps:

### 1. Complete Quests for Big Rewards
– Main Missions vs. Side Quests: While main story missions provide some Coupons, the real goldmine lies in side quests and NPC tasks. These missions often provide quick payouts and lead you to locations brimming with valuable loot.
– Pro Tip: Always check with NPCs for available quests, even minor ones. Completing these tasks can unlock more lucrative opportunities later.
– Early Game Focus: NPCs like the Bartender in the starting areas are great sources of smaller but frequent jobs. These quests can reward you with upwards of 1,000 Coupons early in the game.

### 2. Hunt and Sell Artifacts
– Locating Artifacts: Use an Echo Scanner to detect hidden Artifacts. Search for clusters of anomalies, where Artifacts are most likely to appear. Follow the Echo Scanner’s beeping to pinpoint the Artifact’s location. Approach cautiously to avoid enemies.
– Selling Artifacts: Duplicate or less useful Artifacts can be sold for a significant profit. Vendors in settlements offer the best places to sell loot, gear, and Artifacts. Each vendor may offer slightly different prices, so shop around if possible.

### 3. Sell Unused Gear and Loot
– Inventory Management: Prioritize collecting high-value items. Surplus weapons, gear, and consumables can be sold for extra income. Focus on selling items that are not essential to your survival or progress.
– Grenade Strategy: Grenades are rare and highly valuable. Instead of using them in combat, sell them to vendors for quick cash.
– Consumable Sales: Items like vodka, food, and surplus medical supplies can fetch decent prices. Sell excess consumables regularly to avoid hitting your inventory limit.

### 4. Explore Every Part of the Map
– Hidden Stashes: Hidden stashes scattered across the Zone are treasure troves for players willing to seek them out. These caches, revealed by PDAs, often include weapons, ammo, and other resources. Don’t forget to unload any guns found in stashes to save money on ammo.
– General Exploration: While you won’t find Coupons in abundance when exploring the map, you will get a lot of unwanted gear and junk that you can later sell off. This helps manage your inventory and provides additional income.

### Additional Tips
– Repair Wisely: Only repair gear you actively use to avoid wasting Coupons. This strategy helps maximize your earnings by ensuring that you spend Coupons only on essential repairs.
– Plan Efficiently: Combine exploration with quests to save time and maximize your profits. This approach ensures that you make the most of your time in the Zone, increasing your overall earnings.

By following these steps, you can efficiently manage your resources and accumulate Coupons quickly in Stalker 2: Heart of Chernobyl.
