Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
