DD (away at university) and I both have kindles and she's in my Amazon family so she can read my kindle books.
I bought a book and decided to return it for a refund the day after. Later DD asked if I'd read it yet because it was really good, she'd seen it and downloaded it and read it but because her kindle was then offline it wasn't deleted from her kindle. I didn't know but it was one she had been wanting to read so read it immediately.
Should I buy it again so it's been paid for given that DD read it?
