How are people comparing GPU prices across providers?

I’ve been trying to figure out how to actually compare GPU pricing across different providers and it’s way more inconsistent than I expected. The same GPU can vary a lot depending on region and availability, which makes it hard to know what’s “normal.” This is one of the few things I’ve found so far that at least shows pricing across providers: https://www.mercatus-ai.com/gpu-index Does anyone here have better ways of comparing pricing or other tools/resources they use?
