How to pay for Onsego without a credit card
Like GED.com, Onsego requires online payment with a credit or debit card.
If you don’t have one, you can register online for the American Express Bluebird Card (a free prepaid debit card). Then, you can add funds to your account with cash at any Walmart location.
