You can get heat packs from kensfish.com, wrap heat pack in newspaper or place a piece of cardboard between the plants and the heatpack, otherwise the heat will melt the plants you're trying to ship. Keep in mind...the longer the heat pack lasts, the bigger they are. So 48hr ones are smaller than 72 hr ones. I've found 72 hour heatpacks are overkill for priority sizes boxes and leaves you limited amounts of space.
