Good evening, I want to say that I am not satisfied with the delivery. Indeed, for two orders on Amazon, one was delivered to me at the address indicated, for the other it seems that I would have moved. But this is not the case. I do not discriminate Amazon but the act of delivery. My daughter needs this book to his school, and I'm not delivered on time, because there was failure in the delivery. If Amazon could do something so that I can quickly have the two books I ordered delivery without failure, I would know it grated. Thank you
