Hi Evo,
If you aren't sure you'll be home (And we'll be more than happy to ship any day of the week that is most convenient for you... Just let us know), we recommend having the package shipped to a local FedEx or Kinko's location. It usually arrives before 9 a.m., and they will call you when it arrives. That way it will always be in a climate controlled environment until you can pick it up that day.
We guarantee live arrival and very, very rarely ever have any issues. Our ricordea and zoas are all but bulletproof in shipping. Usually they are already open in their bags by the time you are ready to add them to your aquarium!
Keep in mind that what you might have to pay in shipping, you are almost certainly going to be saving money as compared to buying the same corals from your LFS... We are the divers who collect these corals, so there are no middlemen...
Cheers,
Colin
