You can still ship, I've had a few shipments over the years get delayed for various reasons and not delivered till second day.
BUT....
You need to cover the basics.
1. Use the insulated boxes (may want to either get one with 1/2" or even one with full styrofoam cooler.
2. CHECK WEATHER, both for your area (less important) deliver to area (very important). IMO, the snake will do better if it arrives cold then if it gets too hot. Either way, extreme temps are not good. I held up a shipment to Minnesota for two months last winter....to cold to ship.
3. Get the longer lasting heat or cool packs, plan on the shipment being delayed another day.
4. Pack the shipment well to minimize heat transfer either into or out of your package.
