I ordered 100 juv silkworms and food for $11 shipped too. That was Tuesday night. Nick (the guy that works at silkwormfarms.com) emailed me Wednesday morning to tell me he could ship them that day if I wanted (I picked Monday as shipping day by accident). So I told him yes and they are on my porch this morning when I woke up. So I took them inside and after they warmed up for about 2 or 3 minutes (its 50F today) they are all wiggling and eating. Every single one in the container is alive. And there is a decent amount of food, as well.
Great guy to do business with.
