Order dispatch
In-stock items ordered before 2 PM Eastern typically ship the same business day.
Shipping days: Monday–Friday, excluding holidays.
Product-specific availability and processing times take precedence. Dispatch is when an order leaves our warehouse; delivery timing depends on the shipping service and destination.
We ship to the 50 US states, including Alaska and Hawaii, and to Canada. We do not ship to US territories. We do not accept backorders.
Shipping options and delivery timing
Enter your shipping address at checkout to see the services and prices available for your order. Choose the option that works for you before completing your purchase.
Shipping time is separate from any product processing time. A faster shipping service does not shorten the preparation required for a programmed kit.
Free shipping
Standard shipping is free for orders delivered to any of the 50 US states. Select the free shipping option at checkout. We choose the carrier and service for free shipments.
Expedited shipping is available as a paid option. Shipping to Canada is charged at checkout.
Canada orders
Shipping charges and available services are shown at checkout. The customer is responsible for customs charges, taxes, duties and carrier clearance or brokerage fees. We do not collect those charges at checkout; the carrier or relevant authority may request payment before or at delivery.
Shipping addresses and signatures
We accept P.O. box shipping addresses. Available services are shown at checkout. We do not ship to freight forwarding addresses. Orders placed with a freight forwarding address will be cancelled and refunded.
Check your address carefully before ordering. Contact us promptly if it needs to be corrected. Once a package has shipped, we cannot promise an address change or redirection.
Some shipments require an adult signature at delivery. If your shipment requires one, an adult must be available to accept the package. Contact us before ordering if that may be a problem.
Tracking your order
We email your tracking information when the shipping label is created. A label-created status does not necessarily mean the carrier has received the package; check the tracking link for its latest scan.
Delayed, missing or damaged packages
If your package is delayed, arrives damaged, or is marked delivered but cannot be located, contact us with your order number. Keep the packaging and take photos of any visible damage so we can help investigate. When you provide photos and we confirm arrival damage, we cover the return shipping and replacement shipping. When tracking says delivered but you report the package missing, we will investigate with the carrier. If the investigation cannot verify delivery to the correct address, we will replace the order at no cost. If the same product is unavailable, we will issue a full refund. If the carrier verifies delivery to the correct address but the package is later missing, we review the circumstances case by case.
When the carrier confirms that a package was lost before delivery, we will send a replacement at no additional cost. We handle the carrier claim; you do not need to wait for the claim to be paid before we send the replacement. If the same product is unavailable, we will issue a full refund.
Changing or cancelling an order
Contact us as soon as possible. We will check whether the order can still be changed or stopped.
