You can now buy Charmed 1 (which was released last month) digitally in the Panini official site.
You can also preview the first 10 pages of Charmed #0 from the Volume.
For those wondering, Panini hasn't revealed a release date for Charmed 2 yet (even though they have their previews and release dates for August-October up). i asked them about it and they said they'll "keep us in the loop".
