Check your mail everyday. The only time i bought worms on the net i had put a 'hold at the post office' on the package because it was so hot and i have a black mailbox.
Well they came 2 days early and i just happened to be home because there was a power outage. I had already picked up the mail but went down the hill to check the power line repairs and found that instead of holding the package the post office they had made a special delivery because the box was labeled live animals. They would have cooked if i hadn't had to drive all the way down the hill to turn the car around.
Oh the driveway is 1/4 mile long. So i drive to avoid the 100+ degree heat and the four pawed wildlife.
Good point for the summer. Thankfully we are in the midst of fall and fall temperatures here. My PO box is in a small rural post office, the lady usually holds packages for us as she knows we come once a week at most. Worms are supposed to arrive tomorrow, however we are so rural here I wouldn't be surprised if they arrived a day later.
