Replying to Feeler/good deal?...this years k2 PE and STH 12

i have brand new K2 PEs 179s still in shrink and brand new unmounted salomon STH 12 w 90mm brakes making them a perfect compliment to the skis at 85mm.  these are unmounted so you could put them on fresh where you like em.  i'm looking at $500 for the set.  is that unreasonable?  i would likely put them on a popular purchasing website that sounds a lot like pig latin to be secure unless someone wants to take the plunge direct.  i'm an old dude and not some scammer.  

i bought them and then opted for a bigger ski for myself and simply let my return/refund window expire so now im trying to recoup some of the cash.  i know im a moron.

thanks
