RT Promo iIems?

For the past several days, I've been checking out promo items to have made for the RT convention in April. I can't make up my mind. Of course all of us authors want items that will compel readers to buy a gadzillion of our books, to buy all our backlist and all our future books. We want items the readers will keep and thus remind them of us for a long time into the future. We want items that will stand out in the crowd. And we want items that won't make us go broke. Um... That's a pretty tall order. At least it's perplexing the heck out of me. There's a couple things I'm thinking about. I hesitate to mention which things here because if hundreds of authors haven't already thought about them, I want to keep it unusual. When I'm at a readers' conference, I love to pick up pens. I usually look at the author's website. But does everybody? Hopefully. I definitely don't want to invest in something like a candy bar wrapper that'll be thrown away after one use and at most get one glance, however much appreciated. Bookmarks are another good buy for the money, but there are usually hundreds of them. How many will a reader honestly use and reread? Yet again, what other promo item can you purchase 100 for $17.95? You'll also want to see what Amarinda Jones, Anika Hamilton, Anny Cook, Barbara Huffert, Brynn Paulin, Bronwyn Green, Dakota Rebel, Kelly Kirch, Molly Daniels, Sandra Cox, Regina Carlysle, and Cindy Spencer Pape are up to, so make sure to visit them also. :)
