If you've spent all funds gifted to you by Discovery and your wallet balance is at $0, you can donate to your nonprofit organization of choice by making a personal donation. Please note: each separate donation that you make can be funded by your wallet or your personal funds, but not both. So if you want to donate $50 but only have $25 in your wallet, make one donation from your wallet, then a second donation using your personal funds.
To use your debit or credit card to make a personal donation:
First, click the "My Profile" tab in your wallet portal and add your personal debit or credit card:
You can now use that card to make your personal charitable contributions. You can even use it to set up regular, recurring donations through the system.
