Free money alert: You can scoop up a $20 credit for Prime Day just by trying Amazon Photos for the first time at some point through July 8.

To participate, simply download and boot up the free Amazon Photos app (available on desktop, iOS, and Android). Once you’re signed in, all you need to do is upload at least one picture and turn the app’s Auto-Save feature to automatically back it up. Boom. Done.

Amazon will send you an email within four days to confirm that the credit has been applied to your account, and to provide instructions on how to redeem it come Prime Day (which is on July 12 and 13 this year). You’ll be able to put it toward any $40-plus purchase of products sold by Amazon.com or Amazon.com Services LLC — look for “sold by Amazon.com” or “sold by Amazon.com Services LLC” under the “Add to Cart” button in the right-hand column of product pages.

Amazon Photos is available for anyone with an Amazon account (though you’re limited to 5GB of storage without a Prime membership), so feel free to keep using it even when you’re doing securing that $20 credit. Beyond cloud backups, the app can also be used to order prints and personalize Echo Show and Fire TV devices with your snapshots.

This is just one of many ways you can earn free Prime Day credits this year: Amazon is also doling them out to people who see Lightyear or Elvis in theaters, as well as customers who spend at least $75 on Procter & Gamble products.
