It was, but I know the local Walmart moved it and a bunch of other blu rays (and other merch) to the back before BF started and told people they were OoS. I know all the stores pull that nonsense with their TV's and computers and such, but this is the first time I've ever heard of them doing it for a

ing $10 discount on a movie.
It was also available online, but naturally orders were cancelled left and right. There was actually a small thread about it on Slickdeals lol, nobody who posted ever had an order go through.
Obviously every store is different but AFAIK anybody who didn't go in ahead of time and hide a copy somewhere was pretty much SoL.
At any rate, that "sale" is over now.
