The temp. where the beardies are will depend on the temp outside, yes. If you are planing on shipping in the next week, with the weather we are having right now I would say use a heat pack. Beardies like it quite warm anyway. But you can, and should, always check the weather network to be sertain of the temp. on the day you will be sending for your area and the recievers. This will also help you decide weather you need one or not.
Herps are like pringles, you can't stop at just one.
