In order to qualify for the so-called "Family Pack" promotion, customers will first need to purchase at retail a copy of Vista Ultimate, which carries an estimated retail price of $399 U.S. The deal will not be offered to those who purchase Ultimate preloaded on a new PC, sources said; it will be for customers buying and/or upgrading via retail channels only.
Sources close to Microsoft were sketchy about some of the particulars. The exact price of the additional copies isn't clear: Some believe it will be $49.95 per copy; others, $99.95. Vista Home Premium's current estimated retail price is $239 per copy.
Microsoft is making multiple versions of Vista available on a single DVD, as part of its Windows Anytime Upgrade marketing plan. As a result, users who want to take advantage of the new promotion will be able to "unlock" the additional licenses from their DVD using a software key after paying for the additional copies by credit card, sources said.
