Yes! iTunes will accept your Greenlight card as a form of payment.
Made a purchase already but aren't seeing it show up in your app?
- Your purchase may not show up for 2-3 weeks because iTunes has a unique billing policy, and sometimes they take longer to process purchases. If you have a Spend Control set up for iTunes, make sure you don't move money out of your iTunes Spend Control or delete it until after your purchase shows up!
For more info about iTunes' billing policy, check out their website here.
