Quoting profdlp

They will sell you additional licenses (see the pic in Post #5) for 90CDN (about $80 US). That ain't cheap, but it is about $50 off the regular price.

$159 DVD-Upgrade, $143 for 3 additional licenses for a total of $458 for an UPGRADE - not even full version... NOT my idea of a family pack. Microshaft really knows how to stick it to ya.
