How do I add a credit card?
Log in to your DealMachine account.
Click your name in the [lower-left? — the cancel article says lower-right] corner.
Click Billing Settings.
Click Wallets & Payments.
Click Add Card.
Enter your card number, expiration date, and CVV, then click Save Card.
How do I set a default card?
If you have more than one card on file, click Set Default next to the card you want to use. Your default card is charged for subscription renewals and wallet charges.
How do I remove a credit card?
Click the trash bin icon next to the card. If you only have one card on file, you can't delete it — add a new card first, then remove the old one.
You can delete the default credit card as long as another credit card is left.
