Best Laid Plans

When Where the Dreams End was published, my idea was to have my short story collection, Nine Kinds of Trouble, come out at the same time. My thought was to use the collection as a sales tool for Where the Dreams End. I thought if people got a little taste of my writing in NKoT, they'd come back and purchase Where the Dreams End. It seems I had it backwards and people that have bought and enjoyed Where the Dreams End, come back and purchase Nine Kinds of Trouble. That's very cool, but unexpected. I'll take that kind of surprise any time I can get it. 

So, what promotional ideas have you had? Did they work they way you intended or did you get a surprising result like mine? Share your promotion ideas, successes and discoveries. I'll draw a winner from the comments and send you a signed copy of Nine Kinds of Trouble.
