I've had a few questions about how the card charging works, etc, so let me address that all here.
Basically, you're pledging whatever amount you want, towards the final goal of fully funding my cookbook project. Unlike some other crowd funding sites (which all work differently!), Kickstarter is "all or nothing". If we don't reach 5,000 in pledges by the end date of the campaign, the project doesn't fund, and the book doesn't get created.
Because of this "all or nothing" model, Kickstarter doesn't charge your card until the campaign ends, and ONLY if it's successful in reaching the funding goal. Your card won't be charged (Aside from possibly a $1 authorization charge, which drops off a few days later) until the end of the campaign!
So, if you are considering waiting for payday, feel free to go ahead and enter your pledge at any point. Then, you'll be "in" for any of the backer-exclusive posts that I'll make between now and the end of the campaign... and I'm working on some great exclusive recipes to post for backers!
