Funny -- I almost bought it off backcountry for $100 a few weeks ago, when I needed a pair of 10 DIN bindings for my wife's new skis. I ended up getting her a pair of Salomon 810Tis off SAC, so I didn't buy them, but my thought at the time was that they're selling the bindings for $70, so for $30 more I'd have a set of skis I could mount up if I wanted to. So unless I'm wrong, and assuming that shipping would be at least $30, it's probably cheaper to buy them on BCO than it was to buy them on SAC.
Funnier -- they're $98 and change
on BCO now. But BCO offers free shipping on orders over $50, and if my order history is any guide, SAC always charges for shipping. So unless I'm getting this wrong, it should be cheaper now on BCO than it was on SAC.
