It appears that they get these sent to their stores every so often, so check back on their site. I also some advance open boxes, but they were almost $550.
I was lucky enough to get one at the Madison Heights, Michigan store last Friday for $447 plus tax. It said damaged box. There were scuff marks on the body like it was used, but a label on the box showed it was serviced. The props, battery and camera appeared to be new. The manager made a note about the marks on the receipt, and told me I could bring it back in 15 days if there was a problem, because they will not take it back if it shows signs of a crash. B sure to inspect it before leaving the store. Good luck to the person who gets it!
