Kimber Kable Select

Emojo, as has been alluded to, there are lots of scams in the audio world as there are in the rest of the world.  There are many counterfeit products, Kimber included.  Since the items were purchased in an audio store I would recommend you take them back there or at least contact them to see if they would sell on consignment. If your story is legit (not saying it isn't) then this would be the easiest for you. 

Rodman99999, these cables are 10 years old, doubt he will sell for 70% of retail. I would suspect closer to 50% of retail.  You can try for 70%, but don't expect that much.  These cables are pretty common on the used market.
