Do you consider it a violation of no smoking conditions if you accept an offer with such conditions KNOWING you have a mailman who smokes and that everything which passes through his vehicle ends up reeking of cigarettes? Even though the smokey smell isn't actually the sender's fault?

Yes.

Unless you can take it to the post office personally, bypassing the dragon mailman.

No, but I wrap everything in plastic first.

If things end up smelling like smoke from the mailman smoking, and you plan to give it to the mailman, then yes.  You could drop it at the post office and wouldn't have a problem then.

OK. I am going to have to start turning down smoking conditions I guess. I no longer have a car and I don't know when I will again, so I'm going to have to be doing all my mailing from home until our 3rd car gets back on the road, which at this point may not be until spring.

Do you consider it...?

Ackk. I thought you were asking for opinions. I hope we didn't make you choose one way or the other because of what we said. I was answering your question in light of my feelings on the matter. You will have to ultimately do what your conscience dictates in your situation. It is not a hardship for me to get to the post office, and most times I have to anyway because of the over 13 ounces thingie. Could you possibly do a once a week run or something?

You should complain to your main Post Office.  Tell them he is damaging your merchandise. Your mailman should do his smoking on his own time and in his own home. I had to complain to our PO because all my packages were delivered with such a stink my DH had to open them outside. It stopped.

I think if the book is in a zip lock bag OR any plastic bag that is well taped, it would be fine.  EVEN SMOKE does not go through everything.    But that's my opinion. 

I would complain to the post office. 

I agree with the posters who suggest wrapping the books in plastic.  As a person with allergies to smoke, I would not mind if the packaging smelled smoky, because I just throw it away.  The book-if well wrapped in plastic-would not be affected.  Of course, you can always PM the requestor and tell them of the situation. 

I think the PM is a great idea -- let them know that although the package may have an odor, you've protected the book inside.

We have another postman now who smokes in the car, every one of the packages I got for Christmas smelled awful. A few were in plastic so the items didn't smell once I opened them and took the nasty smelling boxes outside. Wrapping it in plastic would prevent the books from smelling IMO.  I guess most of the postal workers figure they're delivering the mail in their own vehicles around here so they can do as they please. My mail stinks.
