Can you buy apps from Play Store?

These might be some dumb question but I'm considering getting Graphene OS and I'm wondering if you can still buy apps/have subscriptions.

Also does NFC work? ( No google wallet, just normal NFC )

Yes. However, some apps may be problematic due to the new Play Integrity API. See the write up here
