Safe to send snails in this weather?

[LeTigra]

I am desperately needing Assassin snails for my BN plec breeding tank as the pest snails I have are trying to take over the world!
If I were to buy some off AC or ebay, or even here, is it likely they would make the journey by post? Do they travel well even when its cold?
Opinions appreciated

I've just received 3 assassin snails through the post last week. I think as long as they are packaged well enough they should be ok.

Cant speak for assasin snails but ive twice recieved apple snails in frosty weather with minimal casualties (2 out of 20 wasnt bad)
