You can use the $25.00 Voucher code of, "HOLIDAYGIFT2020 " when you buy instruments, and Expansion packs on the Native Instruments Website. I am not sure what else it works on, but it does not work with Komplete or any hardware purchases.
I've purchased six expansion packs since yesterday. I log in and select my item, I apply my voucher code and make my purchase then log out. I then log back in and make another selection and so on....
Thanks Aidan O Driscoll for the heads up!!!
Good luck,
