Dunno. And it may depend on distance. As I send stuff out this summer, I will keep a watch on it. My season is just starting. I don't heat pack, winter send plants. I bet the African violets will give us the best idea. Most of my herbs and weeds go First Class. Actually, I send most things 13 oz. and under, except glass, First Class. With eBay, I can do First Class on line with free tracking. One can't do that with click'n'ship. 4 skinny New England rhizomes go First Class very easily.
I have Celandine going from Maine to Colorado tomorrow. Here are the price options. First Class is based on 13 oz. It will probably be less for the Celandine.
