Yeah....ground shipping from overseas will likely not fair well. I can imagine you would lose 75% or more of whatever they send, but then I am no plant expert, so I could be wrong. If they are known for their plants and have a good reputation, might be worth a shot.
FYI ~> ordered many plants from taiwan --> java moss , java fern, swords .... they all came alive and green ...so i wouldn't worry too much if it's DOA ... their customer service aren't bad at all..
