Norton 360 deluxe different sources

Hello. I live in austria. I have norton 360 deluxe. I have to renew it now and I received an offer 30euro but I found the same product in german website 25e and in amazon 20e which sends an activation code via email. So is it same to buy from Amazon and where can I enter the activation code when I receive it?

I don’t know whether Norton support will still exchange license key.
