Use valid promotions at checkout
Coupons & Promotions
A promotion is valid only when it is displayed by KKSET or issued through an approved campaign. The checkout result is the final confirmation of eligibility.
Where official coupons come from
Official codes can appear on the KKSET website, email, customer-service message or approved partner campaign. Third-party coupon pages can display expired or unauthorized codes.
Common conditions
- Minimum order value.
- Specific product or collection eligibility.
- New-customer or one-use restriction.
- Start and expiry dates.
- Country, currency or payment limitations.
- Exclusion of shipping, tax or custom work.
Coupon stacking
Only one code may be accepted unless the promotion explicitly states that it can be combined. Automatic sale pricing, free shipping and a coupon can follow separate rules.
Why a code may fail
The code may be expired, misspelled, restricted to another account or region, below the minimum spend, applied to excluded products or already used. Capture the cart and error message before contacting support.
Refunds and adjusted orders
A partial cancellation or return can reduce the order below the promotion threshold. Refund calculations may reflect the discount originally allocated to the returned item.
