The details, in plain sight
Halloween questions, answered.
How do I get 20% off?
Add at least £50 of products to your basket. The minimum includes VAT and is measured before discounts, excluding delivery. The 20% saving applies automatically at checkout; no code or email sign-up is needed.
Can I combine this with another discount?
No. Halloween is 20% off regular product prices, never an extra 20% off a sale price. Each product uses the Halloween price or its existing sale price, whichever is lower. Multi-buy savings, coupon codes, welcome codes and other promotional coupons cannot be added.
When does the offer end?
The offer ends at 11:59pm UK time on 31 October 2026. An order must be placed before midnight to qualify. A basket saved before the deadline does not reserve the offer.
Until the last night of October
