Republishing Content, Making It Appear On RSS Feeds Homepage

A lot of the content I post on my site are time sensitive deals. Sometimes these deals re-occur. Rather than re-writing the same post and making a few changes, I’d like to republish the existing post.

That way all the comments stay in tact and I don’t have a bunch of posts basically saying the same thing over and over. At the moment I’m just changing the date on the posts so that they reappear on the homepage.

My problem is that these posts don’t show up in feedly, and it’s not exactly convenient to constantly change the post date. I’m hoping that there is a plugin that allows me to hit republish or something similar.

Anybody know of anything? Site is https://www.doctorofcredit.com if that helps
