# Selling Price Adjustments

{% hint style="warning" %}
📢 **Economy Update** — NPC sell prices are now scaled to each item's original buy cost, keeping zeny flowing fairly and shutting down NPC-selling exploits.
{% endhint %}

What an NPC pays you now depends on how pricey the item is to begin with: the more expensive it is to buy, the larger the divisor applied when you sell it. Cheap items simply can't be farmed for easy profit anymore.

## 🛒 How Your Sell Price Is Calculated

| 💰 Buy Value Range | 🧮 Sell Formula | 🔎 Example Buy | 💵 You Receive |
| ------------------ | --------------- | -------------- | -------------- |
| 1 – 500            | value\_buy ÷ 8  | 400            | 50             |
| 501 – 5,000        | value\_buy ÷ 10 | 2,000          | 200            |
| 5,001 – 10,000     | value\_buy ÷ 15 | 7,500          | 500            |
| 10,001 and above   | value\_buy ÷ 25 | 25,000         | 1,000          |

{% hint style="info" %}
🧾 **Worked example:** an item that costs **7,500z** to buy falls in the **5,001 – 10,000** tier, so it sells for **7,500 ÷ 15 = 500z**.
{% endhint %}

## 🎯 Why We Did This

<details>

<summary>🛡️ Shut down exploits</summary>

No more buying cheap items in bulk and flipping them to NPCs for easy zeny.

</details>

<details>

<summary>⚖️ Keep the economy stable</summary>

Controlled zeny circulation means less inflation and a healthier market for everyone.

</details>

<details>

<summary>📈 Reward real progression</summary>

NPC sales stay a side income — never a shortcut around actual gameplay.

</details>

<details>

<summary>🤝 Encourage player trade</summary>

With NPCs paying only modestly, vending and player-to-player trading become the smarter play.
