I must agree with other users of Classipress ... advertisers not being able to delete their old/outdated ads is a real pain.
It should be an option. Yes, I know they can change the status and hide an ad, but listers want to be able to "get rid" of the ad, and I'm constantly being asked to help. I finally put a sidebar notice that when advertisers area ready to delete, they should contact me and I'll do it willingly. But why isn't this allowed by Classipress?
