This much discrepancy doesn't bode well.
What I would love to see is a button, so that it'll take me to Geico's site with the exact same quote (all the information filled in).
Also, _please_ email us at sayhi at leaky dot com with the email address you used on the site so that we can look into it; that difference is well outside of the norm.
EDIT: Thanks for emailing us and including screenshots. As discussed, we've already identified a few issues (we blame Geico's website), and have added it to the list of test cases for further testing.
