how do you just get English books only when trying to buy them ...
go into advanced search (may only be available on the website) and specify language
If you are in the UK then they will automatically be English.
If you are in some other region then most ebooks will still be in the English language. You should not try to use the Uk amazon shop, it's not for use outside of UK
