We do not accept returns of frozen feeders due to health/bio concerns. We do however guarantee that your feeder order will arrive frozen. We ship with enough dry-ice in the box to keep your order frozen through most delays. If there is an extended delay in the delivery of your order and your order arrives ruined, you may contact us and we will take care of you. We will either reship your order or offer a store credit. If your order arrives damaged with the feeders ruined, contact us and provide pictures of the damage and ruined feeders. Our boxes are very sturdy double wall boxes that can endure quite a bit of rough handling without your order being ruined.
