I do the same, i live in germany and wanted a book from UK, sadly it has 4-5 weeks delivery time but our vacation was a week away. So i downloaded the book, read it on our vacation and had the physical copy a few weeks later deliverd. Later i bought the book a second time when the german version released. With another book i bought for my wife and wanted to read at the same time, i downloaded it and we could both read it and talk about it simultaneously. Some other time i wanted to read a book at home with a physical copy and on my kindle during some time when i was outside in the garden. Cause in a hammock the kindle is easier to hold. Every time i had purchased the physical copy and the illegal download was just for convenience. No harm done.
