In the 5 in 1 pack you find a free code that gives you free access to the site during two weeks.
As far as I know, you cannot buy extra codes.
At least, on this forum we cannot help you. Go to the English site and contact the publisher.

After the two weeks, you can still use the code from your book to do the test exams (togetter with gsm code)

i bought a 5in1 pack and it includes the personal code of course.
i would like to rebuy a personal code if possible because my 2 weeks are finished but my theory exam is in 2-3 more weeks.
