Shipping & Delivery Policy

Orders are reviewed and prepared for shipment within 0–2 business days of payment confirmation. Business days are Monday through Friday, excluding U.S. federal holidays. Orders that require researcher credential review, address correction, or additional order verification may take longer; we contact you by email when that happens.

The following carriers and service levels are offered at checkout:

• USPS Ground Advantage
• USPS Priority Mail
• UPS Ground

If live carrier rating is temporarily unavailable, a single flat-rate standard shipping option is offered instead so your order can still be placed. Temperature-sensitive materials are packed with cold packs at no additional charge.

Shipping is dynamically calculated at checkout. Rates are quoted in real time by the carrier based on your destination address and the packed weight and dimensions of your order, and are displayed in USD before you submit the order. The rate you select is locked to your order at the time it is placed.

If live carrier rates cannot be retrieved, a flat-rate standard shipping charge is shown instead. There is no separate handling fee. Any applicable sales tax is calculated and displayed separately at order review.

Dream Life Labs ships to street addresses within the United States only. Checkout is restricted to U.S. destinations; we do not ship internationally and do not export orders. Orders are also subject to the eligibility rules described in our Purchase Restrictions.

Delivery windows shown at checkout come directly from the carrier and are estimates, not guarantees. Typical transit times after fulfillment are:

• USPS Ground Advantage — approximately 2–5 business days
• USPS Priority Mail — approximately 1–3 business days
• UPS Ground — approximately 1–5 business days

Total time to delivery is processing time plus carrier transit time. The specific estimated delivery date returned by the carrier for your chosen service is shown at checkout and on your order page.

A tracking number is generated when the shipping label is created. You receive a shipment confirmation email containing the carrier, tracking number, and tracking link, and the same tracking information appears on your order page in your account. Tracking events may take up to 24 hours to appear after the label is created.

For carrier delays, packages marked delivered but not received, lost or damaged shipments, or an incorrect or undeliverable address, contact support@dllabsinc.com with your order number and, where applicable, photos of the package and contents. Support hours are Mon–Fri, 9am–5pm PT. You can also reach us through the Contact page.

Address changes can only be made before a label is created. Once a label exists, the shipment must complete or be returned to us by the carrier before it can be reshipped. Refunds, replacements, and carrier claims are handled under our Refund & Return Policy.

All materials are sold for in vitro laboratory research use only and are not drugs, foods, or cosmetics. Orders are subject to applicable jurisdictional, export, and shipping restrictions. See Purchase Restrictions and Research Use Only Terms for full details.

Payment information is processed securely through PCI-compliant payment providers. Dream Life Labs does not store full payment-card details.
