Just to be clear, "Classic Edition" is not the free open-source MySQL that we all know and love. It's a separate product for inclusion in other proprietary products. MySQL has always been a dual-license product, and this is similar to previous offerings by MySQL AB and Sun. The "N/A" price probably just means "contact us so our sales team can squeeze you for all you're worth" -- which is how enterprise software deals typically work.
