I run a site with coupon codes. Nothing's more frustrating than finding a coupon that's expired so I needed a plugin that would remove old codes & avoid irritating my visitors. DishSoap sounded like just the ticket so I tried it out. When the expiration date I set rolled around it expired the post right on time.
I also like that it doesn't delete the posts, just removes them from public view. That way if I just need to do an update I don't have to rewrite the entire post.
It's incredibly easy to use and works perfectly.
Many thanks to the creator of this plugin!
