If you've ever bought anything from STP or signed up for their dealflyer email, you know they have a very active/dynamic couponing/discount code system where they give out specific coupons to you every few days.
They have been were sending me deals with 35% off which seemed to apply to their skis.
On STP, it looks like they got a few shipments of closeout skis to sell off:
Atomic Blackeye Ti with XTO 12 bindings (seems to be 2012 model)
retail 999.99, regular STP price 689.95. After email 35% off coupon-465.42
Cheapest on the internet (with bindings) seems to be still way over $590 or so..
If you use affliate cashback sites you can get a few extra % in rebates on top of that too.
I believe STP has no clue about skis in particular, and the way ski manufacturers puff up their MSRP with huge discounts as the ski gets old, be sure you shop carefully and don't just go by amount saved.
