Shipping & Tracking
Tracking details are provided when an order is prepared for shipment and accepted into the carrier network.
Before shipment
Please confirm the delivery address during checkout. Contact support promptly if an address or order detail is incorrect; changes cannot be guaranteed after fulfillment begins.
Tracking
Carrier scans and delivery estimates are controlled by the carrier. A tracking number may take time to show its first scan after the shipping label is created.
Delivery concerns
If a package is delayed, damaged, or marked delivered but cannot be located, use the contact form with the order number and tracking details.
Returns
Because research materials require chain-of-custody and handling controls, do not ship an item back without written return instructions from RevPep support.
