CUSTOMER INFORMATION

Shipping & Returns

Free shipping: Orders with a merchandise subtotal of $100 or more qualify for free standard shipping.

Here’s what to expect after placing an order.

Order processing

Orders are reviewed and processed on business days. If we need to verify an address, payment, or order detail, we may contact you before fulfillment.

Shipping

Available shipping methods, charges, and estimated delivery windows are shown during checkout when online checkout is available. Carrier delivery dates are estimates and can be affected by weather, holidays, address issues, or other delays outside our control.

Tracking

When tracking is available, it is sent after the carrier accepts the package. Please make sure your delivery address is complete and accurate before the order is fulfilled.

Damaged, missing, or incorrect orders

If something arrives damaged, missing, or incorrect, contact Support as soon as possible. Include your order number and clear photos of the package, shipping label, and affected item so we can review the issue.

Returns

Because storage conditions and chain of custody matter for research materials, return eligibility is limited after shipment. Please contact Support before returning anything. Opened, altered, or improperly stored materials are not eligible for return.

Cancellations

If you need to cancel an order, contact Support before it ships. Once a package has been transferred to the carrier, cancellation may no longer be possible.
