Buy in large quantities by sea

A large number of journals and fanfics are shipped by sea. I bought my CP back. It takes about two and a half months to ship to Europe by sea. I am always waiting for when it will arrive. I am very happy to unbox it. This time, the packaging is beautiful and not broken at all! But one question is, every time I cross the sea and arrive in the UK, I have no way of knowing when it will be delivered to my home, and the local delivery is also very strange? But overall Doorzo is still very easy to use, and the UI is clear and it is good! Moreover, shipping 10kg by sea only costs 8,300 yen, and then deducting points is a waste of money
