Yes just contact the person below you on the list, last person sends to the first person. As far as shipping & when work that out with the person your trading with. I would think that most people will be able to send out today but as someone said earlier whoever your sending to may not want you to send today for some reason. I would think that most of the corals that we will be sending will be able to be sent the 2-day priority and be just fine. I'm not sure for the ones who are sending xenia though, I know i've always heard they don't ship well so if your sending those you may want to use overnight.
