Very prompt and professional, the books were carefully packaged. It's great that I can buy books in Russian on your website! Thank you for your work!

This is one of those times when there are real people behind every purchase. You can feel it! I can really see the love for books and care for the customer that the Polaris team brings to the table when processing, packing, and shipping our orders. My favorite bookstore, thank you!

A wonderful website, the best of all that I know and have ordered before, order processing is fast and delivery is ahead of schedule, I receive answers to all my questions immediately, the books arrive very well wrapped - carefully and with love, it is a joy to order from you, and even free if the order is from 50 euros, I am very grateful to all the site workers for your professional work and love for books!!!
