We have several years of shipping everything from sharks and stingrays, to octopus, and corals. We have always had the same guarantee, Our animals will arrive in wonderful condition, triple bagged and rubber banded to ensure no leaky bags. We use 1" thick formed styrofoam boxes with an outside cardboard box to ensure there is minimal temperature fluctuation and is well protected from the outside weather. Depending on weather we may add heat packs or cold packs, but this is only in extreme weather. In the unfortunate time of a loss during shipping, we require an email with picture of the dead animal, within 2 hours of delivery stamp, and you will receive a full credit to be used for your next purchase. On any replacement, you only pay the shipping. In the unfortunate event there is a delay in the shipping company, we can not be held responsible. we can offer another piece at an extreme discount, but unfortunately no shipping company at this time offers a full guarantee on overnight shipping. We ship on Tuesday Wednesday and Thursday for next day delivery by 2pm. If there is any problems with receiving your package by said time, immediately contact us and we try our best to help facilitate any problems with the Shipping company.
