I'm not that experienced with ebay. What would you normally do - wash them to see if the stain will go and if not return? It's a fairly big brown stain just under the back pocket - unmissable. Warn first that that's what I'm going to do? How about the smoke smell? It really is pretty awful. But I guess it didn't say anything about a smoke-free house, so I don't think I can complain about that, can I?
