Slipstick.com occasionally runs contests or giveaways for our loyal readers. When we do, announcements are made on this website, in Exchange Messaging Outlook newsletter, Outlook-Tips newsletter and website, on Twitter and Facebook. The giveaways are always free to enter but may be limted geographically (due only to export laws).
Recent contests included giveaways for Office 365 Home Premium subscriptions, a copy of my Outlook 2013 Absolute Beginners book, and more.
If you are a vendor and would like to include some of your licenses in my next contest, let me know. The lists for winners for each contest are linked below.
