https://proxysto.re/en/ sells GrapheneOS phones, with worldwide shipping I believe. They do donate a portion of every sale to GrapheneOS. However, you're recommended to install GrapheneOS yourself and not buy it from someone else, so that you know it hasn't been tampered with.

I feel like this glows.

I've been to the store personally. Seemed alright. I can't prove their stuff isn't tampered with, but it's an ordinary store run by a bit of a privacy/self-defense nut.

You can verify it was installed correctly using boot hash+attestation+factory reset. Much easier to just install yourself though. They have instructions for verifying.

Many services sell phones with GrapheneOS preloaded. Can be easily verified but no benefit for most people so it probably doesn't glow.

Proxysto.re seems to list good services as well and minimizes data. Accepting Monero is positive for their trust as well.
