Discount for NI Hardware w/o Software, or how to sell the included TP2?

So with the near release of the Kontrol S2, I’m interested in upgrading from my Vestax TR-1. I don’t want the the larger size or extra features of the S4… but the S2 gives me instant access to the Sample\Cue banks and jog wheels (something I have ended up missing with the TR-1… since I downgraded from CDJ1000s). But I’ve already purchased a full copy of Traktor Pro 2, and would like to get something back from my purchase since the upgrade would give me a 2nd TP2 key.

Does NI offer a discount on hardware, since I wouldn’t need to use the new included Traktor Pro 2 key?

Or can I just sell the new key that I would receive with with the S2?

I think you can only sell the new key
