Update: I woke up this morning and checked on them. Even the stuff that had any signs of life are looking way worse. I emailed the same to fish of hex and he messaged me back saying that the candy cane and the GSP aren't dead and he'll send me a code for the dead stuff.
He claims the GSP is impossible to kill, so I hope he's right. To be fair, it actually still has some tiny hint of purple to it yet. As for the candy cane.... well i disagree.
Lesson learned: hold package at UPS terminal. Although it appears the one closest to my house is only open 330 PM to 730 PM daily?? so that isn't much of an improvement over my typical 530-630 pm delivery time. I also don't think I will order from someone again who won't offer a few days guarantee. Good on him for making this right, however, to be fair I emailed him 3 hours after these were received instead of 2 hours. If he wanted to be a jerk, he could say sorry too late. 2 hours is just not reasonable IMO.
I'm probably going to wait a few more weeks before reordering anything though. I'm not going to chance the weather being an issue again.
