About 4 years ago I shipped an entire pop up display for a 10x10 booth at a convention.
Shipped from my business in Belleville out to Vegas. Got there perfectly. Shipped it back with Fedex (same that shipped it out there), and when it got back, there was a huge gash in the container (meant for shipping the display), with tire marks in it.
I $hit you not, someone let it fall off a dock (by appearances) and then ran it over with a tractor trailer.
They delivered it like that, and the gal who brought it into my store looked at me like there was nothing wrong. She dropped it off and said "See ya tomorrow". I told her "You just hang on there. You're not going anywhere just yet."
They would up buying me a new 2,000.00 display unit after ruining my old one (this was the second convention it went to from the point I bought it).
They all have their flaws. Seems though that UPS has more than the others.
