USA orders: Shipping is always free! It goes via media mail, which takes about 2 weeks to get to you.
Outside-USA orders (international orders): Shipping is free when you order more than $300 and you use this coupon code at checkout: freeship. If your order is less than $300, then shipping a book outside the USA (including Canada and Mexico) costs $20 per book and takes about 2 weeks via airmail.
Faster options: If you are in the USA and want to receive the order faster, choose either the Priority Mail ($7 - takes less than 4 days) or Overnight ($20) shipping option. We process orders at 9 a.m. Pacific Standard Time, so if your overnight order arrives at 10 a.m., it will be shipped the following day, not that day. There is no faster option for non-USA orders.
