I think there are already countless lists like these, but I'll give my two most favorite stores that accept cryptocurrency payments.

Takeaway.com - Has been accepting Bitcoin for years now. You can order food online in many different European countries.

Overstock - They too have been accepting cryptocurrency for years. They even keep part of their payments in Bitcoin and do not immediately exchange everything into fiat.

Really if you're into cryptocurrency yourself, do everything to support these websites. They are a HUGE support for Bitcoin adoption.
I personally use them every month almost and pay with Bitcoin.
