>I have always bought books
>I always bought books
Grammatically I know the difference, I think, but you're still saying the exact same thing, aren't you?
It seems to me the first is continuing and the second has ended.
As in the first one implies you still always buy books, and the second that you used to always buy books.
My understanding is what >>9644127 said.
Neither sounds correct to me desu
>I have always been buying books
>I always used to buy books

It shows. Although you are corect, those are the proper present perfect continuous tense and the imperfect tense, that's not how people would usually say them irl
