Search by zip code issue

For the past 3 weeks or so no new listings appear when doing a search by zip code. The listings that appear today have 8 days or less to expiration. I prefer to purchase locally and use the feature regularly. I've emailed Audiogon support twice with no response. Anyone else having this problem?
@mitchchavis, The problem with the zip code search has been fixed, FYI. :)

Although this is an old thread, but you can try try this:

After you register, and save your searches, you will get instant alert once something comes up that matches you searches.
