Pre-Order Swag

I'm in the process of brainstorming promotions and giveaways for THE DAY BEFORE (which comes out in 6 weeks... eep!) and I'd love to know what you would like.

Bookmarks? Postcards? Gift cards? Nothing at all? What makes you lay down cold hard cash for a book? I mean... other than a promise of a good book. :)

What have other authors done that caught your attention and made you give their books a try?

Light up comment box below and tell me what you want to see for THE DAY BEFORE.
