I figured out why they were discounting them. The academy sports store that I went to had three left. The unit on display and two in back. Both in back had been opened, one was in a box but had a broken key and was filthy with a huge quarter sized gouge mark on the side. The other was not in a box but looked fairy straight and clean. Both were scrapped on the bottom, and covered in dust.
However, they were 30% less than anyone else, so I'll take the discount an exchange for a less than ideal cabinet.
