Dropbox offers a Dropbox Business 14-Day Trial for free. That's the best deal we've seen for this version of Dropbox, which normally costs $15 per month. This trial features 1,000GB storage for five users, unlimited file recovery, unlimited version history, prevention of outside-of-team sharing, and team management options.

Note that you'll need to cancel your subscription before the trial ends to avoid being billed for continued use of Dropbox Business.
