I think it's a self-fulfilling prophecy-type thing -- if one dealer decides to clear out old stock, the others get stuck with nothing moving until he's finished with his, and by then there's no more customers for theirs. So they have to discount, fast.
I jumped on Bayou Lafourche's offer and got a BM Boguszewski Spike; after that, I didn't even look at anyone else's Benchmades, discounted or not.
Of course, I still neeeed a 710 and I like the look of the Griptilian ...
