Terrible service
My order was canceled and they did not notify me, after three days I found out through the account. I immediately placed the order again, requested one-day shipping due to the urgency I had with the book, but to my surprise when I received the email confirmation they eliminated the one-day delivery, I was not charged but what I needed was the delivery immediately, do not pay less for the order, since now you do not know when it will be sent.
