Как загрузить книгу из UK store?
how can I download a book from UK store if I live in Russia?
You can't, you have to be here in the UK and have a UK billing address on your account to use the UK store. If it's a free book then you could try asking the publisher to make it available in the Russian store. If it's a paid-for book then is it available on other ebook stores/apps that you have access to in Russia ?
