On crappy websites

You know, when Orbitz and Kayak.com have been unable or unwilling to show me accurate airfares for the past three or more years, I have trouble seeing healthcare.gov as a particular failing of the federal government.

Seriously, they'll show me a $1500 fare, then when I try to buy it it's evaporated and replaced with a $2500 one. But when I search again? The $1500 is *still there*. And this has been going on since at least late 2010.
