Get $15 for uploading pictures to Amazon Photos

Amazon Prime members can get a quick $15 from Amazon without spending anything. Download the app for desktop, iOS or Android. Then upload at least one photo to the service and you’ll qualify for a $15 credit to use during Prime Day.

There are a few important catches, along with the Prime membership requirement. The $15 credit must be used during Prime Day — between the start of the sale at midnight PT (3 a.m. ET) on Oct. 10 and the end at 11:59 p.m. PT on Oct. 11 (2:59 a.m. ET on Oct. 12). The credit can also only be used for Amazon orders of $30 or more. 

The $15 bonus only applies to Amazon Prime members uploading to Amazon Photos for the first time. If you’ve used Amazon Photos before, you’re out of luck. And for those looking to get extra cash along with Prime Day deals for free, the offer is not available to Amazon Prime trial members.

Amazon says you’ll get an email confirmation of your $15 within four days of uploading your first photos. The deal expires at 11:59 p.m. PT on Oct. 7.
