It will be fine. They package very well with good insulation and a good amount of dry ice. They use ground shipping which is why their shipping is cheap. I have used them for a while, now. I once ordered from them forgetting about a weekend trip that I had planned, and, because of my poor planning, the shipment arrived on the Friday of our departure, a few hours after our flight, of course. When we returned on Monday, they were still frozen solid after sitting on my porch for 3 days.
