In-stock items usually ship within 1 to 2 business days. If an item is back-ordered, we will email you with the expected ship date. If we cannot ship within the time stated at checkout, or within 30 days if no time is stated, we will offer you a new date or a full refund.

Address changes and refusals

Confirm your address at checkout. We can change it only before the order ships. If a package is returned as undeliverable because of an incorrect address, we will contact you. Reshipping is at your expense. Refused packages are treated as a change-of-mind return: product refund only, and you pay the original and return shipping.
