How to sell in the classifieds - I don't want to overdo this

[DGM]

I have had a number of posts out there for a while, and some of them have fallen off the "20 days or less" option in the listing. Before I start putting these items on TAS, I want to make certain that others have a chance to see them.

(1) Should I just update the posts where I still have something to sell? Or is that being too pushy?
(2) Should I delete the posts where everything is sold?

Thanks,

David
