Macro Algae - how long will it last when shipped?

[Reef GE]

How long does macro algae stay alive when being transported. If I ship it to a location in the USA and then have it arrive at my location overseas (6-7 days later) what are the chances of it staying healthy? I'd like to order some OGO red macro algae, but not sure of whether it will reach me alive.

Easily 2 days. Temperature plays a vital role with any delays
Unfortunately and mainly out postal service has become LESS than Reliable for delivery
