Yep I've been disappointed ordering livestock. My first live order I ever had shipped arrived at about 60F, two of the bags didn't even have water in them and I proceeded to watch 2 of the three corals I had bought melt over the next few days. The third coral lasted another 2 weeks and croaked. There wasn't even any talk of credit/refund/replacement. I never ordered from them again and was nervous about getting livestock shipped ever again. In fact I don't think I had anything shipped for about 5 years after that.
I've also had frags shipped freshly cut, unmounted and rolling around in the bags. Nothing like having your $30+ frags RTN overnight all for the sake of a little piece of rock or some styrofoam
On the flip side, I've also had fantastic experiences with ordering stuff. Smart packaging with lots of heat packs and followups by the company I've ordered from. Its those companies that get my business now and I stay away from the others.
