Well, it has been my understanding that the first to post/msg about an item was first in line despite having come to a settled deal. Unless they say they don't know if they want it.
I made an offer because you had not set a firm price, but that signified me wanting it. I also told you to tell me what you wanted if my offer wasn't enough.
To me, if you offer it to someone for a price, and tell them they're first in line. They are first in line until they don't accept it or some priod of time passes. Not because someone else emails in with a good offer before they get the chance to reply.
