I don't know why you can't pre-order 8.04 Hardy Heron CD's from the Ubuntu ShipIt site given that it's less than ten days from its release date.
The site only allows you to order 7.10 Gusty Gibbon CD's. What's the use of ordering outdated CD's that will arrive several weeks later when they will be of no use anymore?
Please, allow us to pre-order CD's of the latest version of Ubuntu.
