alright I'll bite on this one now be nice if I'm way off I know this bunch...lol

could you be referring to Plume? if so nice find regardless of what they may be worth finding them for15 is great. The value to you is all that really counts though there is always someone willing to shell out more than you think. As far as the shopkeeper not knowing how long they have been there that could be quite common depending on what shop it was and how long he had been there. The shop I currently work at had a real disaster in the humidor when I went in so first thing was reduce and replace with more current and in demand lines though the cigars may be worth more, if they are taking up space on the shelves and not selling then they are worth nothing to the owner. Have picked up some nice steals this way myself in the past, and hope that all can find the same luck at one time or another. So there's my 2 cents hope it helps :)
