I just put my first 6-pack of short stories up for publishing via Smashwords and Kindle for $2.99. You'll get 6 stories for the price of 3, a couple of them in previously-unpublished form.
The book "The Light Of An Oncoming Train: A 6-Pack Of Short Fiction" ought to be available from Amazon for the Kindle in a couple days. Smashwords might take a bit longer.
