You may return most new, unopened items within 30 days of delivery for a full refund. We'll cover return shipping if the return is our error (incorrect or defective item).

Expect your refund within about four weeks after handing the package to the carrier — this includes transit (5–10 business days), processing (3–5 business days), and your bank's handling time (5–10 business days).

To return: log in → My Account → Complete Orders → click “Return Item(s)”. We'll email you when the refund is processed.

We ship to most addresses worldwide. Some items have shipping restrictions and may not be available for international delivery.

Shipping & delivery estimates are shown at checkout based on item availability and the shipping method you choose.

Many shipping rates are weight-based. Product weights are listed on product pages; carriers require weights to be rounded up to the next full pound.
