If that's what you're already doing, then never mind! (Though your comment about the status codes suggest you didn't see the advanced-search option to limit the results by status; maybe that'll be helpful.)
You're absolutely right. I did use the advanced option in the past, but have forgotten that lately, but that does not solve the problem of sifting through the entire list for a book nearby. Selecting by country would help tremendously keeping trades less costly (postage). I do know some members do not even enter a country in their profile, but also filtering them out eventhough they might live in your country is not a bad thing.
