Many stores don't even accept a return of more than 100 hrs on it. I agree that 130 hrs should be 2nd hand instead of open box. I believe that you have 30 days to return it. Do it. Don't hesitate. To be honest, i got it as an open box at 930 even before 8350 was out. Right now you can probably get 8350 at around 1100 easily, so why bother.
