The Pennsylvania Poetry Society hosts a poetry contest every year. (This is the 60th one.) This contest has many different categories, including one for haiku, senryu, and tanka. There is a $2 entry fee per poem for non-members, and poems must be unpublished. There are two prizes for each category -- $100 and $75 for category #1 (The Grand Prize), and $30 and $20 for the other categories. All entries must be postmarked by January 15th.
If you're looking for free online reading, new issues of Sketchbook, Shamrock, and The Heron's Nest are available. And a good generational haiku can be read over at tinywords.
For fans of good science fiction and horror fiction, you can currently pick up a SIGNED copy of Charles Gramlich's Cold in the Light, from the author himself. One signed copy of the book is only $8, which is significantly cheaper than ordering an unsigned copy from Amazon would be.
Cold in the Light is a great book, and if there were a sequel I'd buy it in a minute. You can read blurbs about it by people much more famous than me on the Amazon page. Visit the author's blog for information on ordering a copy.
