The move also rewards existing members who've signed up for Apple's Web services. The company is offering a 50 Euro (about £30) discount voucher redeemable against purchases from the Apple Store.
Also up for grabs is a free desktop version of Alchemy Deluxe, and a $5 discount against the registration cost of Bejeweled Deluxe. Both games are available in .Mac member's iDisk software folder.
The company recently released .Mac Slides Publisher and BackUp 1.2 to .Mac members, and will be offering a number of extra features to members making use of iCal on its release later this month.
