What should I say?

[peppy_man]

Hello.
When I ask someone to buy and bring a book to my country,
and say thank you to the person for the kindness,
what should I say?
I pay the money when I receive the book.

'Thank you for bringing the book to my country.'?
'Thank you for buying the book to my country.'?? (But I pay the money.)

Any advice and opinions will be appreciated.

I would say:

Thank you for bringing me the book.

RonBee, thank you for your reply.
I will use the phrase you proposed.
Best regards.
