Books are the next obvious choice! Saifedean Ammous' Saif house would be a great place to start or the Konsensus Network. You could also download  the Bitrefill app and it will have specific merchants that sell products and services that you could buy with BTC.

I was looking at BTC Map around where this person lives...zip. 

What could you buy online that's not techy like VPN services or ppq.ai?

I think the best starting point is to get them to download wallet of Satoshi wallet and send them like 1000 sats at first. Then take them shopping using btc instead of fiat. The best way to onboard is to show not tell.
