How it works
Add the code TREAT20 at checkout and 20% comes off every item in the Halloween offer in your basket. Products in the offer carry the orange "Halloween offer: 20% off" badge. Anything without the badge stays at its normal price.
When it ends
The code works until 23:59 on Saturday 31 October 2026, UK time.
Liners, bundles and the multibuy
If a liner or a bundle item is in the Halloween offer, the code gives you 20% off it in place of the multibuy or bundle discount. Any other liners in your basket still get the multibuy: 10% off two, 15% off three or more.
Already reduced items
The Bold Black items on the Outlet price are already half price, so they are not in the code. Their price is the one you see.
The small print
One code per order. It can't be used with other discount codes, and it doesn't apply to C&C habitats, the Essentials, the Mushroom collection, gift cards or sets of 2. We may end or extend the offer. Questions? Email help@kavee.com
