For a limited time, Amazon Prime members can earn $15 in Amazon store credit just by downloading an app.

How to get $15 of Amazon credit for free

To get the free $15, all you have to do is install the Amazon Photos App and upload a photo, and the $15 will be credited to your account within four days. Seriously, that's all you need to do. The offer is valid from now through 11:59 PM PT on July 7. The $15 credit can only be used during Prime Day 2023 (July 11-12).

If you've never subscribed to Amazon Prime before, you can get a 30-day free trial. Even if you aren't eligible for the free trial, it makes sense to sign up for Amazon Prime right now. Prime costs $15 per month, and you can get $15 back with this promotion.
