Shipping Policy

Last updated: October 20, 2026

About this policy

Thank you for shopping with DUO. This policy explains how we ship your order, what it costs, and what to expect after you buy.

Order Processing

Orders are prepared and shipped by our fulfillment partner within 1–5 business days of purchase (Monday–Friday, excluding U.S. holidays).

Orders placed on weekends or holidays begin processing the next business day.

Subscription orders follow the same timeline from each renewal date.

You'll receive an email with tracking as soon as your order ships.

Shipping Methods & Delivery Times

Standard (USPS): arrives 3–5 business days after your order ships (about 4–10 business days total, including processing).

Express (USPS Priority): arrives 1–3 business days after your order ships (about 2–8 business days total, including processing).

Available shipping methods and estimated delivery times are also shown at checkout. Delivery times are estimates, not guarantees, and begin once your order ships. They may be affected by carrier delays, weather, or other events outside our control.

Shipping Costs

Shipping charges are calculated at checkout based on your order weight and selected shipping method.

Standard: from $8.

Express: from $15.

*For one-time orders, free Standard shipping applies to orders of $75 or more after discounts, before shipping and taxes, delivered to eligible U.S. addresses, when the Standard shipping rate is $18 or less. Express shipping on one-time orders is charged at checkout.

For subscription orders, both Standard and Express shipping are free when the selected shipping rate is $18 or less. If any shipping rate exceeds $18, you pay the full shipping rate, not just the amount above $18. Higher Express shipping tiers therefore remain charged. The available rates and your shipping charge are shown at checkout. We may change or end this offer at any time; the terms shown at checkout apply to your order.

Order Tracking

Once your order ships, we'll email you a confirmation with a tracking number and link. Please note tracking information may take time to update after you receive it.

Multiple Shipments

Orders with several products may arrive in more than one package. You won't be charged extra shipping when that happens.

Shipping Destinations

We currently ship to addresses in the 48 contiguous United States and Washington, D.C. We don't currently ship to Alaska, Hawaii, U.S. territories (including Puerto Rico, Guam and the U.S. Virgin Islands), APO/FPO/DPO military addresses, or outside the United States.

Address Accuracy

Please check your shipping address at checkout, and contact us as soon as possible if you need to correct it. We're not responsible for orders delivered to an incorrect address entered at checkout. If an order is returned to us because of an incorrect address, contact us and we'll help arrange reshipment (additional shipping may apply).

Lost, Damaged, or Delayed Packages

If your package shows as delivered but you can't find it, arrives damaged, or is significantly delayed, contact us within 10 days of the delivery date (or expected delivery date). We'll work with the carrier and, where appropriate, send a replacement or issue a refund.

Order Changes & Cancellations

Need to change or cancel your order? Contact us as soon as possible. We may be able to accommodate changes before your order ships, but once it's in transit we're unable to modify it. Refunds for cancelled orders will be processed promptly to the original payment method where possible. To cancel a subscription, see our Purchase Options Cancellation Policy.
