I know I've posted here many times (click on the label at the bottom to see other posts on POSTCARD FLASH). Anyway here is a place you can submit.
Postcard Poems and Prose Magazine needs very short fiction. (225 words or less) Tight prose written in active voice that grips the reader from the opening sentence is certain to catch our attention.

Our guidelines to submit are tabbed to the home page.
ALSO check out HOOT
HOOT is a monthly literary magazine. On a postcard! We publish current fiction, non-fiction, poetry, and book reviews all at or few than 150 words. Give a hoot and tweet us a submission!
ALSO http://postcardshorts.com/We're looking for original material, about 250 words or so - as much as you could more or less fit on a postcard.
Postcard shorts is open to all genres of flash fiction.
