Here are some more cost-effective shipping methods recommended as below,
I. If you would like cheaper shipping method, Swiss Post is an excellent choice.
II. If you would like fast delivery, DHL is a great choice, get tracking information very soon and timeliness. Delivery time is 3-5 days.
Так что не Почтой России единой...
