Offer ends September 30: $299 Upgrade to QuarkXPress 8 — from version 3, 4, 5, 6 or 7!

Quark’s $299 upgrade offer ends on September 30, 2009. This industry-leading upgrade program offers QuarkXPress 8 for $299 to registered users of any version of QuarkXPress — all the way back to version 3.

The upgrade is cross-platform, so even if your older version only runs on Windows or Mac, you can upgrade and use version 8 on either Windows or Mac.

Even if you’ve lost your registration information, Quark makes it easy to upgrade: you can either provide proof of purchase or complete an online “missing serial number” form at http://8.quark.com/quarkupgrade/missingserialnumber.html. Quark maintains a database of serial numbers based on the information provided in the form, and may still be able to locate your record.
