    Hello! The service is excellent. I had to wait for the book I needed, but the delivery was amazing! It took me from LV to Hamburg in one week! The books are wonderful: the publishers did a great job, the binding, the photographs, and the paper were a delight!
    Polaris offers great discounts and bonuses, including birthday ones!
    I look forward to new arrivals!
