The post office is a little upset with me, as well as my mail lady. I had to go pick up one box that was sitting on the outside and I got one package that was wrapped in a plastic grocery bag.
If you are mailing wingbones, please drop a little borax in the bag with them. If shipping frozen, still put the borax in them. Heat builds up in a zip-loc bag, due to the rotting flesh on the bones. And, if at all possible, try to ship so they don't have to sit over the weekend.
Thanks,
Mark
