For the more "mature" crowd...and don't everyone look at me...here is a small publisher that caters to baby boomer types...hence the name Silver Boomer Books...
They have a submission call page, and from what I can see generally have a few short story compilations in the works. These old pensioners are a bit "frugal" I'll have to say...if they publish your story they'll throw you ten bucks and a copy of the book...but, it just might be your chance to get in print...
