1. The landing page - 30% clickthrough
2. Subscribe page - 30% clickthrough
3. Checkout page - 6% conversion.

On the checkout page, you just enter your shipping address, sign up (because it's a subscription), and you're done. I have a 100% money back guarantee and a norton trust badge. I don't think I'm doing anything obviously wrong, but 6% speaks for itself.
