Amazon has a 1-year Subscription to Dropbox Plus – 1 TB of Storage for $79.20. Dropbox is rarely discounted!
The subscription increases your storage at Dropbox to 1 TB (from the free 2 GB.) That’s enough to create a complete cloud archive for most photographers. Last time this deal was offered, Dropbox support said this could be used to extend an existing subscription: “If you have an existing Plus or Professional subscription and redeem a license key, your Plus or Professional billing cycle associated with your license key will automatically start on your next renewal date. You will not be charged again until the Plus or Professional billing cycle associated with your license key expires.”
