ScanUK

Complete guide on our SCAN module

Use the ScanUK module for Scan’s UK website. Normal attempts checkout, Monitor watches for stock, and ATC only adds an item to cart. Start with one small setup so you can understand the task statuses before adding more.

Quick Start — Recommended Setup

1. Prepare your checkout profile and working proxies. Check the product’s purchase limit before running.
2. Create a ScanUK task group, choose Create Task and select normal.
3. Select your profile and Checkout Proxy, paste the full Product URL and set the item Qty within the retailer’s limit. The current Delay starts at 3000 ms.
4. For random restocks, enable Watch Task and create a monitor task with the same Product URL. Start both tasks. For a timed release, use Normal with Watch Task off unless release-specific instructions say otherwise.
5. Watch the task statuses and verify any order with Scan. An item added to cart is not a completed purchase.

Preliminary Checklist

Create and save your checkout profiles in Stellar. These contain the billing, shipping and payment details used by Normal mode.

Save and test your proxy groups. The existing Scan guidance recommends testing both ISP and residential proxies. Quality varies by provider; use a small setup first and adjust delays if connections fail or proxies are blocked.

The existing proxy resource is Stella Proxies. Using more than one provider can help you compare connection reliability.

Your cook group can help with product URLs, SKUs and release instructions. Verify that the input matches the task mode you selected.

Respect Scan’s published purchase limits, which may be one item per person or household. Orders can be cancelled for exceeding those limits. Creating extra profiles does not change the retailer’s rules.

Accounts and Sessions

The current ScanUK forms do not have an Account or Session field. Normal uses guest checkout with the selected profile; you do not need to select a saved Scan account in the task.

Supported Modes

• normal: attempts the full checkout using your profile.
• monitor: checks stock and signals matching Normal tasks that have Watch Task enabled. It does not place an order.
• atc: adds the item to cart only. It does not complete automated checkout.

Normal Mode

The screenshot below shows ScanUK Normal mode in Stellar 4.0.

• Name: optional label to help identify your task.
• Mode: select normal.
• Profile: required checkout profile containing your billing, shipping and payment information.
• Checkout Proxy: proxy group used for the checkout attempt.
• Product URL: the full Scan product page link. Do not replace it with the ATC-mode SKU.
• Delay: milliseconds before retrying after an error. The current default is 3000 ms; the earlier guide suggested about 3333 ms. Adjust for proxy quality and connection stability.
• Qty beside the product settings: number of items requested in one order. The default is 1. Stay within the purchase limit.
• Start Time / End Time: optional scheduling for when the task should run.
• Watch Task: enable to wait for a matching Monitor task. Leave off for an independent Normal task.
• Qty at the bottom: number of task rows to create. This is different from the item Qty above.

Monitor Mode

The screenshot below shows ScanUK Monitor mode in Stellar 4.0.

• Name: optional task label.
• Mode: select monitor.
• Monitor Proxy: proxy group used for stock checks.
• Product URL: use the same full product link as the Normal task that should receive the stock signal.
• Monitor Delay: milliseconds between stock checks. The form defaults to 3000 ms; about 5000 ms is the earlier starting recommendation. Increase it if your proxy connection is unstable or blocked.
• Reset Delay: milliseconds before monitoring resumes after detecting stock. About 5000 ms is the existing starting recommendation.
• Start Time / End Time: optional task scheduling.
• Qty at the bottom: number of Monitor task rows. Monitor has no Profile or item-quantity field.

ATC Mode

The screenshot below shows ScanUK ATC mode in Stellar 4.0.

ATC means Add to Cart. After it carts the item, finish checkout manually. Choose Normal when you want Stellar to attempt the full checkout.

• Name: optional task label.
• Mode: select atc.
• Checkout Proxy: proxy group for the cart attempt.
• SKU: the product code. The current hint gives 50SCAN90FE as an example. This field is different from Normal and Monitor’s full Product URL.
• Delay: retry delay in milliseconds; the current default is 3000 ms. Adjust for proxy quality.
• Start Time / End Time: optional task scheduling.
• Qty at the bottom: number of task rows. ATC does not show Profile, item Qty or Watch Task fields.

Product URL and SKU Examples

Normal and Monitor use a full product page URL. The existing example is:

https://www.scan.co.uk/products/palit-nvidia-geforce-rtx-5090-gamerock-32gb-gddr7-ray-tracing-graphics-card-21760-core-tbd-mhz-boost

The existing graphics-card listing is: https://www.scan.co.uk/shop/computer-hardware/gpu-nvidia-gaming/all

ATC uses a product SKU such as 50SCAN90FE. Use the code for your intended item from the release instructions; do not assume the example code is the product you want.

Monitor + Normal Example

For a random restock, create one Monitor and one Normal task with the same Product URL. Enable Watch Task on Normal and start both. Normal displays Waiting for Monitor Ping until Monitor detects stock and signals it to begin checkout.

With Watch Task off, Normal works independently: it checks the product, adds to cart and attempts checkout. For timed releases, follow the release instructions and generally use the checkout task without waiting for a monitor.

FAQ

Does ATC complete the order?

No. ATC only adds the item to cart. You must finish checkout manually after it carts. Use Normal for a full automated-checkout attempt. Always check for an order confirmation before treating a cart result as a purchase.

Why are there two Qty fields in Normal?

The upper Qty requests items per order. The bottom Qty creates task rows. Start with both set to 1 while learning the setup.

Which proxies should I use?

Test working ISP and residential proxies with a small task count. The earlier Stella Proxies reference is preserved here. No proxy type guarantees a successful checkout.

Common Errors and Troubleshooting

• Waiting for Monitor Ping: Watch Task is on. Confirm that a Monitor task is running with the same Product URL, or turn Watch Task off if you want Normal to work independently.
• Product not found or invalid input: Normal and Monitor need a full Product URL; ATC needs the SKU. Check for extra spaces or a link to a category instead of the product.
• Proxy or connection errors: test the proxy, try another working group and increase the delay. Avoid adding more tasks while diagnosing an unstable connection.
• Item in cart but no order: ATC does not complete checkout, and stock may disappear before Normal finishes. Check the task status and your order confirmation.
• Order cancelled: review the retailer’s purchase limit and your profile details. Do not assume additional task rows or profiles allow additional purchases.
