Selling parts and lack of manners.

in my adds , I state that my price is including shipping in the lower 48. I will ship only to Canada after getting a quote, but that is it. so far , I have not sent anything out of the states

You see Lance, that would be great if I were only selling one part at a time, but many is the time, especially recently, when a buyer will say ill take it, then in PMs will ask if I also have this or that, and I do so I work out a bigger box, maybe completely different in shape and size to accommodate a completely different part, and end up packing everything twice, or more!

I currently have a member who is needing multiple items now, 6 to be exact, that range from 52" long headliner bows to 20" wide rear panels, and 4 other items that will fit into that box! I would love to box up every item I have just once and shelve it all and just grab the box and go, but it ain't that easy! I'm in the business of helping members get the parts they need for their cars, and if it means making these jigsaw puzzle packages work, that's what I do!

Why does this matter to the thread at hand? Well, its taken me and the buyer over a week to consummate this deal and it ain't done yet, so in the interest of this thread, what should I do if there were other buyers who wanted the original item? Should I message them all, or just post in a thread contrary to the wishes of the threads intended message?
