Sale list updates

I know we can add an updated date to our sale list. But if there is a update thread the new post will show results when someone searches for posts since last visit. Which is all I do on forums, I assume many others do the same.

Would it be better to do it on a seperate thread like this or on our individual sales threads?

This idea works good.

But if everybody has their own "sales thread" they just make another post to add more stuff.
