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.

I'm one of the technical reviewers of this book. I can say that I've enjoyed reading every chapter of this book. It is full of examples, suited for both beginners who never developed anything in ExtJS or experts who just want to learn new concepts of ExtJS version 5. Book includes chapters with creating the whole pallet of GUI elements, concepts like MVVM, MVC, and creating reusable code.The chapter I was enjoying the most was "Chapter 4: It's All about the Data", where authors gave a lot of great examples with working with data, AJAX calls, mappers, validators, relationships, etc. For me it is the most valuable part of the book because most of my applications are data-driven.This book has everything one developer needs for creating the enterprise-level software with ExtJS.

Ext JS framework has enormous amount of functionality therefore most beginners would be overwhelmed with that. Although Sencha offers various learning material, learning Ext JS is still a difficult task."Learning Ext JS" is a light in the dark for many beginners who want to get an overview of this huge framework.This book introduces many aspects of the Ext JS, sometimes concisely, and sometimes in detail. Especially, the description of fundamentals (class system, component lifecycle, data packages, etc) is well-organized. I can assure you that you will begin with Ext JS smoothly.Plus, many supplement tips is embedded in a lot of places. It would be useful for not only beginners but also seasoned Ext JS developers.

The book gives a descent overview of the framework, but leaves gapping holes at very important intersections.1.) For instance, not enough detail on MVVM implementation in extjs, it's such a big paradigm shift in ExtJS 5+, but the author only dedicates 2 pages in the book to it. This leaves you needing much more.2.) When considering details on the store...it shows you how to add, remove, filter, getById, but doesn't take a look at how to build additional basic queries. Again, leaving you wanting more.I'm not happy with the book, but it's a shame, that there is so much lacking in terms of learning extjs.
