Alfie Dog is an online market for short stories, which plenty of my womag-writing friends have been submitting their stories to, judging by the number of names I recognise in the list of authors!
The site allows single stories to be downloaded for a small fee to the reader. The author gets royalties of 50% of the download fees after banking costs are deducted. Not much but better than nothing. They'll accept previously published stories, as long as you own the copyright.
They'll take stories of any genre except porn, erotica or excessively violent. 500-15,000 words.
