I'm wondering what is a safe overnight/daytime temperature range for the area that I have to ship a BP to? Someone is interested in buying Togetic, my youngest BP who is currently about 300g. But the buyer lives in Minnesota, and their overnight HIGH is only 35, which I'm assuming is way too cold.

The reason is that where I am is in the 80's now, so obviously I can't put in a heat pack. Things would be easier if we both lived in a cold area lol.
