What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

Messora does a fantastic job of reviewing basics of the MVVM development pattern. As a seasoned JavaScript developer who’s used Knockout on a daily basis for a few years and is interested in developing highly testable Single Page Applications (SPAs), this book was of great value. Best practices are clearly identified, and a thorough explanation is provided for each. Ever wondered how to adopt separation of concerns in the JavaScript world to avoid spaghetti code and why it’s a good idea to avoid using jQuery as the cornerstone of your web application? Ever wondered when to choose BDD over TDD to satisfy your testing needs? The answers are found within.Third party libraries such as Jasmine, Gulp, Karma, Phantom, and Postal are introduced. Coming from a Mocha and Grunt background myself, it was worthwhile to see the differences in Jasmine and Gulp, respectively. If you’re just getting started with Jasmine or if you want a refresher course on writing testable JavaScript, consider this book. It’s also a good read for those coming from a jQuery background who are beginning to explore the plethora of MV* frameworks/libraries out there.

The author does a great job of diving into the MVVM pattern, Knockout.js, as well as a host of technologies and frameworks that can be used to create automated tests for a single page application, including Gulp, postal.js and Jasmine. The writing is crisp and clear, and the book as a whole was a joy to read. Highly recommend.

Robert Gaut Feb 06, 2015

I was very pleased to serve as a reviewer on this book. The book is very well-written and is packed with a ton of useful information and practical techniques. The Knockout.JS sections are very clear and approachable to beginners and advanced developers alike. The book especially shines when it comes to unit testing Web apps using Jasmine and the sections on Node.JS, Gulp.JS, Karma, and Phantom.JS are equally impressive. Using the libraries and techniques described in this book have definitely improved my daily development workflows. I highly recommend this book!
