Goodies and Give-Aways

I'm going to begin with a flat out confession (don't worry, this sounds much more dramatic than it is): I'm not sure which goodies make the best give-away treats for the wonderful readers that I get the opportunity to meet and speak with. I'd love to find the perfect gesture of appreciation (no, not bribery) for those who show interest in my books, but sometimes this is easier said than done. Bookmarks, of course, are fabulous, but most authors give these out. Wouldn't it be great to do...
