Or you can do a wonderful job of packing and marking the contents only to have the box get caught in a sorting device at the post office and tear everything into shreads. The letter carrier brought such a box this spring, and she said, I can't believe they want me to deliver this. It was all shredded and broken. Funny thing is there were some day lilies in it that came out great, growing with no problem, and the some of the iris rhizomes were beat to death, but others were OK. They were all the same variety, so they should be fine. but it was a nasty looking mess all stuffed into a large plastic bag with a form letter included explaining that it got caught in a sorting machine, and they were sorry for the incovenience.
