Can I use a digital gift card to pay my credit card bill?

NO. 

Please check with your credit card issuer to determine what they consider to be valid forms of payment, but in general merchants will only allow gift cards to be used for redemption toward merchandise. 

We have had too many instances of someone trying to pay their Kohl's (or Lowe's or Macy's etc) charge with a digital gift card, and then being stuck with that gift card. We want you to have a great experience, and this one is not fun. This message is also included in the terms and conditions of all of our gift cards.
