Who knows Tom. I originally thought it was a legit sale, and if Greg Harris (above) hadn't had his order cancelled then I wouldn't have questioned it. I mean, they've done 50% off on these bags before so you'd think if it was an error they would have fixed it up last time. Having said that, it seems that many online sites *do* make the same mistake twice!
But economically it doesn't make sense any more than the 40% off backcountry.com sale did. Actually this sale is a little more nuts than that one. Obviously they could have sold these bags at 30% off with no problem at all, but they ended up selling them for about double that discount. Even if you want to clear stock, with bags like this you can do it easily with a 25% discount from a reputable dealer like moosejaw. No need to give them away for $135!
