I haven't yet had a reason to try, but here is what I found:
- Open your web browser and go to: www.kobo.com/redeem.
- Click Select under the type of card that you want to redeem.
- Enter the PIN printed on your Walmart receipt. Note: For Gift Cards, scratch the back of the card to reveal the PIN.
- Click Submit. Note: If you redeem a Digital Audiobook card for Instant Credits, you'll need to sign up to an audiobook subscription first.
- Click Continue with Walmart.
