I am not sure how widespread this is. In fact, it may be extremely YMMV as I have only found this price at 1 store in all of Minnesota (Blaine). That being said, if I can help 1 person get this deal, I've done my good deed. Good luck!
Also- Their "New Lower Price" of $79.99 (If you can't find one for $40) is the cheapest price i've found for these.
I have been keeping my eye out for one of these at a good price. I know this specific garage door controller is compatible with Smartthings, Wink, and any other Z-Wave hub.
Really, its just a rebranded Linear one:
