# Auto-extend end time
### ℹ️ What is "Auto-extend end time" option?
**Popcorn bidding,** as known as A**uto-extend end time** feature helps prevent last-second bidding by automatically extending the auction when a new bid is placed near the end time.
When enabled:
If a bid is placed while the remaining auction time is less than the **Trigger when time remaining is less than** value, the auction end time will automatically be extended by the **Extend by** value.
This can happen multiple times during the auction.
***
### 🛠️ Set up "Auto-extend end time" option
1. Open the app > click **Auctions** > create a new auction or open an existing auction
2. In **Additional** **options** session, turn on **Auto-extend end time**
3. After enabling the option, 2 settings will appear:
* **Extend by**\
The amount of time added to the auction each time the auto-extend rule is triggered.
* **Trigger when time remaining is less than**\
The remaining time threshold that activates the extension when a new bid is placed.
4\. Click **Save.**
***
### 💡 Example of how it works
#### Example
* Auction end time: **4:40 PM**
* Trigger when remaining time is less than: **5 minutes**
* Extend by: **2 minutes**
#### Scenario
At **4:36 PM**, the remaining auction time is only **4 minutes**.
A new bid is placed\
→ The auto-extend rule is triggered\
→ The auction time is extended by **2 more minutes**
So instead of ending in **4 minutes**, the auction will now end in **6 minutes** from the current moment.
If another bid is placed again while the remaining time is less than **5 minutes**, the auction will continue extending by **2 minutes** each time.
***
### ✅ Benefits of Auto-extend End Time
* Prevents last-second bid sniping
* Gives all bidders a fair chance
* Encourages more competitive bidding
* Can help increase final auction prices
