That could mean a lot of things. Is the snake you purchased one of the sick ones? If so, it shouldn't be shipped until it's been treated and is healthy - and honestly, I'd QT it for a lot longer than normal in that case which essentially means he won't be breeding this season. So, ASAP could be another month or so if it's sick.
I guess you could try to find someone local to him to go look at the snake and make sure it's healthy before it gets shipped to you, if you can get the seller to agree.
