I'm wondering how the colder weather effects how we ship things. I remember everyone in the summer worried about their shrimp overheating, so the cold should be good for them. But how about fish? And plants? And snails? I imagine it should actually be better--the coldness would slow down their metabolism, and thus make everything less active and less stressed during shipment. What when does it become too cold? I'm assuming that packages aren't being left on front porches for a day, but going through the normal USPS system.
