We do not ship Friday for delivery on Saturday, and Fedex is closed on Sunday.  If we shipped on Friday and your package had a shipping delay, you would not be able to get your package until the following Monday which would give the coral very little chance to survive.  If you are not home Tuesday - Friday during business hours, we can have your shipment held at a local Fedex for pickup.  It will be held safely in room temperature, and you can pick it up at your earliest convenience.
