I was thinking, in the old days, when traders come into town, their inventory is random, yes, but the last time they came by, you can ask them to try to find something. So, what I propose is that you can ask the traveling merchant for one specific item that there is a possibility of him selling at the time, and there would be a 50% chance of him selling the item you asked for the next time he comes around. He should also say something along the lines of, "Sorry, I could not find "name of item you asked for". No one was selling that in my travels." the first time you talk to him if he does not have the item in question.
