I decided to order myself some business cards from Vistaprint. That is where I get all my promotional items. Not that I have tons of promotional items!
It may seem odd for an author to carry business cards, but many times I've been caught off guard by someone asking about my books. In the past, I've directed them to Amazon. Now, I'll have a card directing them to my blog.
I've had bookmarks and postcards printed before, but they are only good for book giveaways and book signings. They're not really something you would carry around in the event you meet an inquiring mind.
Here is my new business card design. I should receive them next week.
