All packages are sent by certified mail (balík do ruky) to the school address. If you fill out your phone number when you place your order, you will receive an SMS message with the package number during package delivery. Then you can watch the package online at the Czech Post portal and you know exactly when the package will arrive. Because the package is sent to the address of a school, it may be accepted by another responsible person, such as a janitor, a lady or a deputy director, etc. You can be sure that the package will arrive and that you do not have to pick it up at the post office if you are absent.
