As a die hard tester, my first question would be, "what price points did you test?"

$299, $399, $499?

For example, you said you have a 0.6% conversion rate and $99 price point point. Perhaps your conversion rate at $499 would drop to 0.3% but even so you just dramatically increased your profit

Often times mispricing (either too high or too low) is why startups fail.
