I've heard that authors should have business cards, and I've seen mixed commentary on whether bookmarks are worth buying/distributing.
And I've seen a variety of swag suggestions on blogs--pens, sticky notes, lip balm, mirror compacts, etc.
So, as a newbie author with an ebook, I'm wondering what types of swag get the most "bang for your buck."
What has worked for you, either as an author doing promotions or as a reader at conferences/readings, etc.?
And what stuff are you likely to just throw out or not even pick up?
