Order handling

Processing, shipping, and delivery timing.

This section explains how orders are typically processed, what shipping method is used by default, and how delivery timing should be understood.

Processing

Orders placed before the daily cutoff shown at checkout are typically processed same day Monday through Thursday. Orders placed Friday through Sunday are processed the next business day.

Shipping method

UPS 3-Day Select is the default shipping option. Typical delivery is 2 to 4 business days depending on carrier routing and destination.

Free shipping

Free shipping may be available on qualifying orders over $200 when that option is shown at checkout.

Delivery estimates

Carrier timelines are estimates, not guarantees.

Delivery estimates come from the carrier and may be affected by routing, weather, peak season, and broader carrier network conditions.

Estimate only

Carrier-provided delivery estimates are not guaranteed and may vary based on conditions outside our control.

Delayed UPS 3-Day Select shipments

If a UPS 3 Day Select shipment has not arrived within 5 business days and the delay is not weather-related, we will investigate and will typically reship or refund.

If the original package shows up later

If we reship and the missing package later arrives, the customer is expected to refuse delivery. If refusal is not possible, we will send a return label.

Address accuracy and returns

Please review order details before submission.

Shipping accuracy matters because address changes may not be possible after processing, and research products are generally final sale once shipped.

Address accuracy

Please verify your shipping address before submitting the order. Once an order has been processed, address changes may not be possible.

Returns

Due to the nature of research products and quality control requirements, all sales are final once shipped, except where required by law.

Shipment issues

If there is a problem with the shipment, including damage, missing items, or incorrect items, contact us promptly so we can help.
