Ride it like you stole it. then tell your girl nice job and slap her on the ass. or whatever you like.
Honestly, contact DWC and see if they're willing to budge on the new vs blem argument. BTW a "dealer" thats putting boards on ebay may not be in the best standing with CWB. But i wouldn't count on CWB doing much. Not product issue, so there's no CWB obligation at all, unless its through DWC. Since its "new", maybe they'll work with you.
