Thanks for that, I've been able to get Stable Diffusion running locally with ROCm so it looks like it should be possible then.

I just found out this was foss yesterday, and really want to start playing with it on my system. Is it GPU-agnostic? I have an AMD card and don't see any mention of GPU support or CUDA requirement on the github docs.

Most smaller shops use some well-known third party to handle the payments, and you can tell as you are redirected to their site when it's time to enter your card details. Some even use Amazon Pay if that's the only one you trust.
