I [Sean] have been an Amazon Prime member for a couple of years now. Why?
There are certainly other benefits, but those are the two I take advantage of most often. However, Amazon just added a new benefit that's perfect for us photographers:
Yes, you read that correctly – unlimited photo storage. *yay!*
From Amazon:
"Store your photos safely in Cloud Drive and you can access them anywhere, from almost any device by signing in with your Amazon account. Cloud Drive offers free mobile apps, secure access from any computer, and it's built in to all Fire devices.If you're not already a member of Amazon Prime, now would be a great time to sign up. If you are already a member, you can start uploading photos to your Amazon Cloud Drive Account.With Prime Photos, the photos you've previously uploaded to Cloud Drive and photos you upload in the future will not count against your Cloud Drive storage limit."
