Orders are typically processed and shipped within 1–2 business days (excluding holidays and carrier delays). Delivery typically takes 2-4 business days.

At this time, shipping availability depends on checkout eligibility and destination. If international shipping is not available, checkout will restrict options accordingly.

Once shipped, you’ll receive an email with tracking details and shipping updates as soon as your order is processed.

We use FedEx 2 Day for street addresses (no P.O. Boxes) and USPS Priority Mail for P.O. Box addresses only. The carrier is automatically selected based on the shipping address entered at checkout.

Certified Package Protection is an optional checkout add-on that provides coverage for qualifying delivery issues such as a package being lost, damaged, or stolen while in transit. Protection must be selected at checkout and cannot be added after an order is placed.

If Certified Package Protection is not selected at checkout, the customer assumes responsibility for delivery risk once the carrier marks the package as delivered. We strongly recommend using a secure delivery address.
