So, your sole reason for not wanting it was that it was stinky. Ok. Understandable.
But, that is the chance you take when buying used, especially when you made the deal knowing it was a no guarantee, no return deal.
arch2 makes a good point; if it’s that important to you, why didn’t you ask if it came from a smoke free environment?
Now, if you, prior to purchase asked the seller if it came from a smoke free home and he told you yes, then you would have a legitimate beef.
But you didn’t. So you don’t.
