Here in my place in Germany you can get up to 100€ bills from the ATMs. Some shops do not accept 200€ bills, more have no restrictions.

My boycott seems not to work out.

It was not that much. From: https://www.kystens.no/nyheter/nekter-a-selge-drivstoff-til-amerikanerne-vi-har-et-moralsk-kompass/2-1-1786648 relevant part translated: “I believe we delivered approximately 3,000,000 liters to them in 2024. It is simply moral support.”
