It`s true that some pubs will allow you to use the stories with no fee. The problem comes in when you attempt to "republish" the article which is essentially what happens on the Internet. They consider your use of the aritcle in its entirity on your website as republished, rather than having a link back to the news site, which obviously has no implications.
I would always be careful and look into this as I`ve had clients in the past get a frightening phone call asking for a lot of money in fees.
Now, if you`re simply making copies for your press kit or to hang in your place of business, it shouldn`t be a problem. I do suggest going to a printer, not Kinko`s (who will ask if you have rights to the article), to get copies. Sometimes you can slip into Kinko`s and do it yourself.
These are some of the issues my clients and me have run into over the years. Always best to be safe than sorry.
