    Great seller. This book was packaged so nicely, and was well protected on its journey to me. Shipping was more than fair on the pricing the book is big and heavy. And the book came as described; maybe even in better than expected condition. And I got a great deal on it too. Super stoked!! I surf San O frequently and can’t wait to start reading it. Thanks again!
