Amazon has been incentivizing Prime members to use Amazon photos as their Cloud storage service of choice with occasionally offering gifts of on-site credit when they upload their First picture or video ... The Company is taking this Prime Day (and the week following) to push another promo, offering $15 if you download the Amazon photos App and give it a try ... Google Photos discontinued free storage for lightly-compressed photos and videos at the start of the month, so it's fairly Smart of Amazon to gin up some help for its service which allows unlimited full-resolution still backups — there's a 5GB cap on video which can be expanded with a subscription fee.
