AI Summary
- Check that the code applies to the UK store, selected model, variant, currency and promotion dates.
- Code stacking is confirmed only when the actual checkout total falls under the current terms; an old campaign page is not proof.
- Compare the final payable amount after the official sale, code, delivery and tax.
Decision table
| Situation | Practical choice |
|---|---|
| Code accepted and total decreases | Save a dated checkout screenshot before placing an order. |
| Code rejected or total unchanged | Check region, excluded variants, minimum spend and any existing code. |
What to do
The current Desworthy Des10 offer record states an extra 10% off UK-store promotional prices through 31 October 2026, UK time. Those are the campaign's stated terms, not a completed checkout for your basket. Record the selected variant, subtotal, code response, delivery and final total before paying. Combining with a sale price does not establish permission to combine two coupon codes.
Diagnose the code using the basket totals
| Basket field | What to save | What it establishes |
|---|---|---|
| Store and currency | UK domain and GBP | Regional context |
| Product variant | Model, colour and optional footrest | Exact eligible item |
| Base subtotal | Sale price before code | The starting comparison |
| Code result | Acceptance/error and changed subtotal | Whether it visibly applies |
| Delivery and final total | Same address and options | Whether the payable comparison improves |
The current Des10 offer record should be read alongside the exact retailer basket. If another automatic discount is present, record it before entering Des10. Compare the totals with identical items and delivery options; do not compare a standard chair with a footrest package or switch currencies halfway through.
Example only: a £249.99 subtotal reduced by 10% would become £224.99 after rounding to pennies, before any delivery changes. That calculation is not evidence that Des10 applies to a particular item. If the basket does not change, keep the error text and ask the seller about eligibility. A percentage code, a sale price and a retailer stacking policy are distinct facts; Black Friday or Amazon Prime Day cannot establish today's UK-store code behaviour.
Frequently asked questions
Can it stack with Black Friday?
Check that event’s terms and the actual basket; do not assume.
Why does an accepted code not lower the price?
Confirm the exact product variant and any pre-discounted-price restrictions.
Can I enter Des10 on Amazon?
Des10 is published for the SIHOO UK store. Do not assume an Amazon order can accept it; an Amazon-specific promotion requires its own terms.
What if the promotion has expired?
Remove a "verified" label until current terms are checked again.
