well to the point of if the box had been opened, maybe check for multiple layers of tape? if the box had been resealed I'm sure there would have been two layers of tape with different cut lines or even some sort of damage to the box from removal of a tape layer? not that it really matters at this point as the situation has been resolved by a refund for the missing coral.
I’ve purchased from Jason before on numerous occasions. Have to say that he always had my interests first as a customer/buddy and took care of any discrepancies that were on his end of the sale. Open and honest. Sucks that FedEx messed up. Hope the corals are ok.
