In 4 or 5 years of shipping ball morphs I've only ever had one "DOA". I say "" as it was not really DOA. 3 years ago I shipped a box with 2 or 3 female yb's and 2 or 3 female pastels (back then a $10K box) in the winter. The receiver got the box that had 2 heat packs in it and rather than opening it put it in his snake room with ambient room temps at 85, did not crack the box until the following morning. One of the female pastels was dead. Being able to, I replaced her.
