Microsoft offers 15GB of online storage for free when you sign up for Microsoft OneDrive. Even better, iPhone users can bag an extra 15GB when they activate the auto-upload feature for their camera roll. That beats our July mention (which didn't include the iPhone bonus) as the best general freebie offer we've seen for OneDrive. Deal ends September 30.

Need more space? Microsoft also offers 1TB of OneDrive cloud storage for $30/year or $2.50/month. That's $30 off and tied as the lowest price we've seen.
