Microsoft offers 3 GB of extra free SkyDrive space for US college students
SkyDrive is a great way to back up and store files in the cloud, and access everything from your tablet, computer or Windows Phone. SkyDrive is a free service with 7GB of storage. From students (or anyone else for that matter) 7GB might not be enough.
If you're a college student you can get an extra 3GB on top of that. All you need to do is head over here, enter a valid .edu email address, and a free storage code will be sent your way.
There are a few catches though. The extra storage space is only available for a year from redemption. Codes are limited to one per person and the code must be used by December 31, 2013.
