Quark has extended its offer until 31st January 2011 to QuarkXPress customers who are using any version of QuarkXPress to upgrade to QuarkXPress 9 for £279.

All current and prior users on QuarkXPress versions 3 through 7 can upgrade to the newest version of QuarkXPress 9 for the standard upgrade price, which is typically applied to upgrades from version 8.

To take advantage of the special offer, users must have a valid, registered, and activated serial number for any version of QuarkXPress. Upgrades can be purchased through Quark Authorised Resellers, the Quark Store, and Quark Customer Service.

Customers that are unable to locate their previous QuarkXPress serial number may still have the opportunity to upgrade their licenses.
