as long as you guys order atleast 5 its all good and yes they would have to ship to one addy to get the combined discount so lets say 4 of you agree to each buy 5 corals you are at 25 and get them for the $13 each price so each person pays $13 x 5 = $65
that make sense?? and if you get them in and anyone doesnt like theirs or already has some of them just do some trading you all will have paid the same for each piece you see
