Follow the link in Ripplinger's sig, and although it states at the top "Try Free for 30 Days" it lists four options on the left:
60 GB - $7.49 / month
100 GB - $9.99 / month
250 GB - $24.99 / month
5 GB - Free
So click the bottom option and you'll get 5GB plus an extra 500MB for using the referral link for no cost.
