Shipping rates and delivery estimates

For orders delivered to the United States, both free and standard shipping use the same estimated delivery schedule:

  • Order preparation: 2 business days.
  • Carrier transit: 5–8 business days after dispatch.
  • Free shipping on orders $150+: estimated total delivery in 7–10 business days.
  • Standard shipping ($6): estimated total delivery in 7–10 business days.

Prices are in USD. These total estimates run from order placement to delivery and already include both order preparation and carrier transit; do not add the preparation time again. Business days are Monday through Friday, excluding public holidays.

Available shipping services, charges, and destination-specific information are shown at checkout. Any delivery date or range shown at checkout, in tracking, or by a carrier is an estimate rather than a guarantee. Weather, customs review, carrier disruptions, remote destinations, and other events outside our control can affect delivery.

Tracking your order

When an order is dispatched, we will email tracking details whenever the selected service provides them. A tracking link may take time to show its first scan after a label is created or a parcel is handed to the carrier.

Customs and import charges

Shipping availability varies by destination. Customs procedures, duties, import taxes, or carrier fees may apply depending on the destination and service. The amount and method of collection are determined by the checkout, carrier, or local authority. Review the information shown at checkout and any notices from the carrier or customs authority before accepting a charge.

Address changes and delivery problems

If an address or order detail is incorrect, contact us as soon as possible with the order number and the correction. We will check the order status, but we cannot guarantee a change or cancellation after preparation has begun or the parcel has been transferred to the carrier.

If the parcel remains delayed, or tracking shows delivered and it cannot be located, contact us with the order number and tracking details. We will review the available information and explain the next step; a carrier investigation may be required. For damaged, incorrect, or incomplete orders, please include clear photos of the item, packaging, and shipping label and keep the item and packaging while we review the case.

Returns and contact

Return eligibility, the 30-day return window, return shipping costs, and refund processing are explained in our Refund and Return Policy. Please contact us before sending anything back.
