Trembles is a fairly new horror magazine that wants poetry and short fiction. Submissions must be emailed, and payment is $2 for poems and flash fiction (up to 1000 words) or $5 for stories up to 6000 words. Contributors will also get an electronic copy of the issue they appear in.
Also, if you haven't read David Dunwoody's cool zombie novel Empire, you can pick up a heavily-discounted overstock copy from Amazon.com for just $6. (If you're not familiar with the book, you can read my review of it over at Helium.com.)
