We love that you're interested in purchasing a gift for your favorite reading fiend! Unfortunately, Radish is not able to offer gift cards at this time. This is because Radish does not handle payments -- all of that is owned and processed by their provider (iTunes Store or Google Play).
If you're looking to support someone's reading habit, you can always purchase a generic iTunes Store or Google Play Store gift card and they should be able to apply that to a future Radish payment.
We also have merchandise for sale, which you can check out here!
