General trading guidelines

So I've had a fair amount of trading experience over the past few months and thought I'd review my general trading guidelines that I'll be following. First, and most importantly, I do not care what is offered, I am not "interested" in anything, except something that has bit more value than what I'm offering. There are really only two things I will not trade for: weapons of any type or cash. I'm not trying sell any of these items until I get close to when I'm leaving. Beyond that, I would prefer something that I can list on Craigslist, however I will certainly consider any offers.
These trades aren't necessarily on a first come, first serve basis, I'm willing to wait some time for a good offer, but I do have a general time limit so I'm looking to get rid of all my current items.
