This is stupid. There is no real way to shop and bring down health insurance costs in the US. It's tied to your job, meaning you would need to get many job offers, and turn them down when you find out the actual insurance costs until you find one that's better, and ignoring other employment factors.
And then everything can change the next time open enrollment comes around. Don't like the deductible, time to start the job search again! Oh, and the deductibles are probably about the same at all the other companies, anyway.
It's just a stupid system from top to bottom, locked into place because our political representatives are completely uninterested in governing.
