As we often hear, very little is ever really free.
These seminars come in the area occasionally and I believe one came through here a month or so ago where free gifts, meals and supposed education is offered.
Here is a link for a recent "free seminar" to make money on the internet, including eBay. Attendee beware. http://www.denverpost.com:80/technology/ci_8552046
It you are wanting a free meal and have extra time on your hands, it might be interesting to attend, but leave your wallet somewhere else. I went to one in Nashville for a motivational and investment seminar. Did not get anything free but it was interesting. Luckily the lines signing up were long and I was still hungry, so I did not sign on the dotted line.
