These days it's more important than ever to be smart about how you spend your money, so here's an easy way to get Spanning Sync for free:
Use a Discount Code
When you purchase Spanning Sync, use a discount code to get $5 off. If you haven't already gotten one from a friend, try SpanningSyncDiscountCodes.com.
Refer a Friend
After you've made your purchase, click "Refer a Friend" in the Spanning Sync pref pane to find your personal discount code.
Share Your Code
Share your code with your friends, family, coworkers, blog readers, tweeps—anyone who uses Google Apps and a Mac.
After Four Referrals, Spanning Sync is Free
Every time someone uses your discount code we'll send you $5. If just four people use your discount code you'll get $20, making your one year Spanning Sync subscription effectively free.
Of course this isn't only available to new customers. No matter how long you've been a Spanning Sync customer you can start at Step 2. If you have any questions, just leave a comment here.
