Looking for WP PLUGIN SUGGESTIONS

I am looking for a free WP PLUGIN that will automaticly update ads from affiliate programs like AMAZON, EBAY, CLICKBANK, or CJ.

Idealy I could produced content of a broad nature to cover a micro niche, and the plugin would be always updating the latest models or releases of products talked about in the content.

Looking to produced sites that I don't have to update myself all the time.

Any suggestions?

Thanks for your time BHers!
