Frequently asked questions

How long will my order take to arrive?

Counting from the day you order, most orders arrive within 6–10 business days. That is 1–2 business days to get your order packed and sent, plus the delivery time for the shipping option you pick at checkout:

  • Economy — $7.90, 5–8 business days after dispatch
How much is shipping?

  • Economy — $7.90, 5–8 business days after dispatch
Can I cancel or change my order?

Write to us as soon as you can. While an order is still being processed — normally 1–2 business days — we can cancel it or correct the shipping address. Once it has been sent to be packed we can no longer stop it; after that, use the return process in our Refund policy.

How are large or heavy items delivered?

Large items ship by freight carrier. The carrier calls the phone number on your order to book a delivery window, so please make sure it is one you answer. Freight deliveries take longer than parcel shipping; the estimate is shown at checkout. If a large item ever needs to go back, email us first — we send you the pickup quote before anything is booked.

Can I return something?

Yes. You have 30 days from delivery to ask for a return, as long as the item is unused and in its original packaging. Email us with your order number and we will send the return instructions.

How do I track my order?

You get a tracking link by email as soon as the carrier scans your parcel. The link can take up to one business day to start showing movement.

My tracking number does not work. What now?

A new number can take up to one business day to appear on the carrier's site. Some items ship from our supplier's warehouse under that warehouse's own number — for example one starting with TBA — and those often never show up on a carrier page at all. Use the order status page linked in your order confirmation email instead. If nothing has changed there after 48 hours, email us with your order number.

What happens if my order has not shipped within the time you promised?

If we cannot ship within the time stated above, or within 30 days when no time is stated, we will notify you and offer you the choice of agreeing to a revised shipping date or cancelling your order for a full refund.

How fast do you reply?

We answer email within 1 business day. Business days are Monday to Friday, 9am–5pm Eastern Time; messages that arrive at the weekend or on a public holiday are answered on the next business day.

Which payment methods can I use?

The payment methods available to you are shown at checkout. Your card details go straight to the payment provider — we never see them.
