AD is a security nightmare. EntraID requires internet but at least allows zero trust with diverse configuration and importantly without storing or holding session tokens or passwords locally.
For my company, the only blocker is file share, which can be migrated. All our with integration use ldap and can be migrated to openid. Luckily we don’t have more AD integrated stuff.

This reminds me of a video I saw where someone committed to this. New phone, use free offers, put stuff in cart but don’t buy, GPS in low income or low spend areas. They got someone from Craigslist to do much of this work.
It worked. I don’t remember channel or where they compared afterwards, though.
Seems like here it’s store based not individual customer based. Maybe you can get others to join you. Buy only the cheapest items, and the other items will get cheaper.
