Here's a warning for anyone who ships plants by priority mail - pay attention to the size of the box. I had only a vague idea that Priority Mail prices now factor in the size of the box until my wife told me a box she shipped for me had cost $25 because of being so big. It wasn't that big and weighed barely more than a pound. I tried to ship another box yesterday and was told it would be ~$30 because of its size. I brought it back home instead. This box was only 14" x 14" x 14", a size I've used before without trouble, and weighed a little more than a pound. I looked at the USPS website and learned they're using dimensional weight pricing for long distances, meaning large, but light packages are priced as if they're heavy. I followed their formula and found my 1 1/2 lb box would cost the same as if it weighed 17 lb. After some cutting and taping, it was a 22" x 7" x 7" box and cost the expected $7.50 to go to CA. The moral of the story is to make sure boxes don't exceed a cubic ft, which is the size where dimensional weight calculations take over.
