Before you order
Delivery How long will this take to arrive?
Most orders arrive within 4–12 business days of being placed. That covers 1–2 business days to prepare and dispatch your order, then 3–10 business days in transit depending on where you are. These are estimates based on what our carriers normally achieve, not guarantees. A tracking link is emailed the moment your parcel leaves us.
Read the shipping policyReturns What if it isn't right for me?
You have 30 days from delivery to start a return, for any reason. Email us first and we'll send the return address within 24 hours on business days, then ship the item back within 14 days. Items need to be unused and in their original packaging wherever that is still possible. Return postage is paid by the customer — unless the item arrived damaged, defective or incorrect, in which case we cover it.
Read the return policyRefunds When does the money come back?
Once your return reaches us and passes inspection, we confirm by email and refund the original payment method within 5–7 business days. Depending on your bank or card provider, it can take a further 5–10 business days to appear in your account.
Read the refund policyTracking Where is my order right now?
Every order ships tracked. Use the link in your dispatch email, or enter your order number on our tracking page at any time. Carriers usually need 1–3 business days to register the first scan, so an empty page straight after dispatch is normal.
Track an orderPayment Which payment methods can I use?
We take American Express , Apple Pay , Google Pay , Maestro , Mastercard , PayPal , Shop Pay , UnionPay and Visa . Which ones you see at checkout depends on your device and region — Apple Pay only shows on Apple hardware, for instance — so whatever appears at checkout is what we can take. Payments run over an encrypted connection and we never store card details.
