I ordered business cards today. Why you may ask?
There have been many times I wished I had something to hand out with the name of my book on it while chatting with friends and/or new acquaintances. It'll give them something concrete; hopefully longer lasting than the conversation.
I also plan to use them when I hand out free passes for ebooks. Smart, huh? Well, before I get all up on myself, I must admit that Vista print managed to talk me into more than the 250 business cards. I also got an engraved card holder, 5 t-shirts (also with my book name on them) and a couple of pens. Not bad for a day's work.
