for 440 clicks I would expect to have 0 sales... so your problem is in the website design not the people who clicked
Even i have the same problem i had leads but leads are not showing. I think they need purchasing leads.
Some of those have a really bad CTR. Is your traffic targeted and what is the source? Google, Yahoo, or other... I would get the CRT up (dropping all under 1%) and give it 1000 clicks before judging the conversion ratio...
