It sucks that it showed up like that! I can say that Insurance through USPS and UPS is a total joke, I have made one claim with each of them and neither one did anything except give me the run around, I don't have a fed ex near me so I can't comment on them but I wouldn't expect anything different.
I work in a very large warehouse that handles 1 million plus boxes per day I and can tell you that any place that handles a lot of freight will treat it poorly. If it doesn't say glass on it it will be thrown, stepped on, have many other boxes stacked on top of it and so on, sometime even if it is glass that happens to it. With places like USPS, UPS, or Fed ex they handles so much freight that if they damage 10% (random number) of it they feel thats an acceptable percentage as long as they rest gets though ok.....Sad but true!
