I bought a new 32" monitor about 2 years ago that when I unpacked it, it was clearly an open box item. The way it had been packed was extremely unprofessional, tape was haphazardly wrapped and twisted around the stand and cords and things that normally come in plastic bags weren't bagged.
They've been shipping the wrong items lately too, twice in the last year when I order something that has multiple selections like color, scent or flavor etc I'll sometimes get the wrong item sent. I've done more Amazon returns in the last 2 years than my previous 15 combined.
