### **Preliminary Checklist**

Before setting up tasks on Scan UK, make sure you have everything below prepared:

* [ ] **Profiles**

> Create and save your checkout [profiles](https://guides.stellaraio.com/stellar/navigating-stellaraio/what-is-the-profiles-tab/how-do-i-add-a-profile) under the **Profiles tab** in Stellar. These contain your billing, shipping and payment info.

* [ ] **Proxies**

> - **ISP proxies** – Recommended for some of your tasks
> - **Residential proxies** – Recommended for majority of your tasks
>   * Save both proxy groups under the **Proxies tab** in Stellar.
>     * If you're looking for proxies, check out [Stella Proxies](https://guides.stellaraio.com/stellar/getting-started-with-stellaraio/stella-proxies) for high quality ISP and Residential proxies

* **Cook Group Access**

> Optional but recommended. Your [cook group](https://guides.stellaraio.com/stellar/getting-started-with-stellaraio/cook-groups) can help you find product URLs, SKUs and early restock alerts.

{% hint style="warning" %}
Scan is known to be very harsh and can cancel orders if you go over the purchase limit. Adhere to the limit set, most likely 1 per person per profile. Use multiple profiles for the best amount of success, with different emails, cards etc.
{% endhint %}

* Which **Mode** do I use?
  * **Normal mode** is your checkout task is to be used for normal checkout flow
  * **Monitor mode** will only monitor and ping your Normal mode watch tasks when they detect the item you're monitoring is in stock
  * **ATC mode** is used to only add item(s) to your cart, this is not full ACO mode. For fully automated checkout, you should be using Normal mode
* What does **Profile** mean?
  * Select a Profile you want to use and that profile information will be used when checking out items
* What type of **Proxies** should I use?
  * You need to use high quality proxies, usually ISPs but can also use resis

    If you're looking for proxies, check out [Stella Proxies](https://guides.stellaraio.com/stellar/getting-started-with-stellaraio/proxies) for high quality ISP and Residential proxies
* What is **SKU**?
  * For example: <https://www.scan.co.uk/products/palit-nvidia-geforce-rtx-5090-gamerock-32gb-gddr7-ray-tracing-graphics-card-21760-core-tbd-mhz-boost> The link below is where you can find all the graphics cards; <https://www.scan.co.uk/shop/computer-hardware/gpu-nvidia-gaming/all>
* What is **QTY**?
  * The number of items you want in one order
* What is **Delay**?
  * The time in milliseconds the bot will retry to checkout after it encounters an error

    You can start your delays around `3333` and adjust accordingly due to proxy quality
* What is **Monitoring Delay**?
  * The time in milliseconds the bot will monitor the product

    You can start your delays around `5000` and adjust accordingly due to proxy quality
* What is **Reset Delay**?
  * The time in milliseconds the bot will monitor the product again after it has detected the item is in stock

    You can start your delays around 5000 and adjust accordingly due to proxy quality
* What is the **Watch Task?** checkbox?
  * The **Watch Task** option allows your checkout task (e.g., Normal mode) to work together with a **Monitor mode task**. Here's how it works:

    * If you check this box, your **checkout task** will not monitor for restocks directly. Instead, it will wait for a **Monitor mode task** (with the same SKU) to detect a restock
      * Once the Monitor task detects the restock, it will "ping" the checkout (with the same SKU) task to run. The checkout task will then add the item to your cart and proceed to checkout

    When using the **Watch Task** option:

    1. Start your checkout task. It will display the message: **"Waiting for Monitor Ping."** This means it's ready and set up correctly
    2. When the Monitor task detects a restock, it will automatically trigger the checkout task (with the same SKU) to run

    If you leave the **Watch Task** checkbox **unchecked**, the checkout task will act independently. It will monitor the SKU itself, add the item to your cart, and checkout directly

{% hint style="warning" %}
Using Watch Task is highly recommended for restocks because it allows the Monitor task to do the heavy lifting. This improves performance and helps avoid overloading the site.
