New Home screen

I contacted the creators of Nova Launcher because I want the full version. They have both an google play upgrade as an input code upgrade.

Since I dont have any google service anywhere I contacted them to ask how to get such a code because I dont have any google service. This was their reply:
"You would need to purchase the app via the Google Play Store, then once you have, email us a copy of the receipt and the email you used to purchase the app with, then we can give you a Direct License to use since you don't have Google Play Services."

How do I buy it if I dont have any fucking google service?

Nova Launcher...
