Not that I'm necessarily sticking up for Coach, but I think that crushed box is due to handling from the carrier, not Coach. Due to my job, I receive packages daily and every once in awhile I see this kind of damage and same as you, I will have perfect packages along with a damaged one. My UPS driver did say sometimes boxes are shoved at their warehouse or fall off stacks which causes this kind of damage, the telltale sign is the black streaks on the bottom.

I know my Coach item orders that come from JAX go thru three stops/exchanges/depots before it gets to me and damage could easily be done at any of these exchanges.
I'm sorry this happened to you.
