Box is offering 25GB of free storage in a special promo
There are some caveats though, so be prepared. It needs to be linked to new account and it has to be for personal use. Also, there is a 250MB file size limit which is congruent with the current free service offering.
There is no word as to when this deal ends, so if you could use some storage and can handle the terms, it might not be a bad idea to sign up for some serious free cloud storage right away. Box has apps for iOS, Android and Windows Phone, so you will be able to access your stuff anywhere. Click on the source link to get signed up.
