I happen to be a Spyderco dealer, and as of 1/2/16, you won't be seeing the same sort of deals on Amazon due to implementation of a MAP policy.
Advertised prices will not be allowed to be more than 40% off of MSRP. Dealers can sell at any price they desire. I can meet pretty much anyone's deal on their knives...
ETA: I'm also qualified as a "Restricted Item" dealer, so if you're active military or LEO, I can order their automatics for you (although they're currently on back order).
