The idea of Newegg refusing to sell to me because I don’t live in California is insane from an American perspective but that’s what the EU has to live with - mindfactory, komplett, etc will not ship across state lines. It’s a single market in name only, as far as distribution and sales. In practice the only “single market” is customs and currency, and even then there’s edge cases.

It is a very weird overall market where you have these strong consumer protections but also backed by low competitiveness in retail and distribution which leaves margins for supply chains to accommodate this.
