Donation app - Get discount when donating

Shopify Apps
1

Hi, i’m looking for an app that lets our customers donate when they check out. And when they donate X amount they get an discount code they can use for the next time. Maybe the discount is sent out thru an email after the purchase?

Any idea of a solution for that?

Were you able to find an app that does this? If not, do you think this is a requirement that other users will be interested in too? It would be rather easy for us to create an app that accomplishes this.
