Audiogon etiquette question


first - APOLOGIES - I know this isn't the right forum subsection but there seems to be no appropriate section to post under.

My problem is this:
I've been writing a seller (twice now maybe?) for the last 30 or so hours about an item they just posted for sale. I told them I wanted it and asked if it was still available and how to proceed. But no answer - I guess they COULD be away (?) but it seems odd to me. Is there any sort of process anyone can recommend to follow? I"m a bit frustrated here.

Call the police and have them issue an APB on the seller. If that doesn't work, file a missing person's report. It probably wouldn't be a bad idea to hire a PI as well.
If the ad can still be viewed, the item is still available.
Like Viridian said, make an offer.
Agree that making a firm, binding, official offer is the way to proceed. I would not assume it is still available, as many sellers list on multiple sites. Audiogon sellers unfortunately learn the difference between an actual offer and an interest in purchasing at an unstated price.
