They only have one shipping option, so it doesn't matter. They ship overnight or as fast as possible, because the vaccine is extremely temperature-sensitive and loses its potency if allowed to get warm. So they ship it on ice and fast. It comes with a syringe, needle and everything else you'll need.
This site has good instructions with pictures:
