Unfortunately Kickstarter doesn't allow for a local pickup option. This gives you a few choices when it comes to backing the project:
1) Select a tier and pay for shipping anyways. I can always still hand deliver the book.
2) If you want to avoid shipping costs completely, you can pledge without a tier (scroll to the top of the page and put in the equivalent value of the tier you want) and just message me directly saying you'd like for a local pickup.
Either option works, and either way, all the money goes directly towards the campaign, even shipping fees.
