I bought the English version from Amazon and even with shipping it cost much less than it would in local bookstores.
The book came in a very nice packaging but it’s probably just gimmicky.
The recipes however, weren’t really up to my expectations. They only had 4 macaron recipes and the instructions were pretty repetitive, making the book thicker that way. Some steps were not very clear. For example, they mentioned using sugar but did not specify which sort. I suspect that some important words were loss in translation, literally, as this book was originally written in French.
They have significantly more recipes for tarts and choux (pronounced as shoo) pastry instead.
Overall I do not really think this book is worth the hype.
