GoodAPI Plant Trees Clean Seas

This is the best tree planting app I've come across. The integration on the website is much better than Ecologi and others. The key difference is that you can quickly and easily add a banner to every product and checkout pages letting people know about the initiative. The support is fantastic, and they are always looking for feedback and ways to develop and improve the app. Since we added this app in June, they've already implemented some really helpful improvements.
