More than not,most are damaged do not being packaged properly.Most of my hundreds and hundreds of shipping experiences have been good. Two notable failures though. One guy was too lazy to find a big enough box and let the neck of a quart soda stick out the top (well, it was covered by the box's flap). Needless to say, the neck didn't survive. More recently, Holabird Auctions sent two hutches, unwrapped in a box. Both bottles were basically crushed glass by the time they made it to me. One hutch was common, but the other one was rare. To his credit, Holabird refunded everything. I've also had a number of bottles mailed to me in plain (unpadded) envelopes and they made it just fine, perplexing and lucky as that is.
