Hi ebonyimani,
I'm very sorry to hear about that. About a year ago, there was indeed an option for buying the curriculum directly from the Little Reader Touch app, but that option is no longer available. We'll make sure to make it more apparent that the curriculum can't be purchased directly from the app in time for the next update.
To further clarify for you, these are the things you need to get the full curriculum in the app:
1.
Little Reader (PC) license key for the curriculum you want - for the English curriculum you can get this by buying at least Little Reader Basic (the download-only version will do)
2.
iAccess for Little Reader Touch - this will unlock the course downloads that correspond with your Little Reader (PC) license keys in the Little Reader Touch app
** The items above are sold separately at the
BrillKids Online ShopYou are not required to actually install and use Little Reader (PC). As long as you have the two requirements above in your BrillKids Account, you will be able to download and play your curriculum lessons from the Little Reader Touch app. The lesson content in the app isn't subscription-based, so you may rest assured that it wont expire or disappear after a certain period of time or after you've finished the curriculum.
Should you decide to get a Windows PC or if you decide to install Windows on your Mac in the future, you can definitely install Little Reader (PC) and use the license key you bought. Your license key is valid for life, regardless if you install the PC software or not.

Unfortunately we are unable to help regarding your iTunes card. If you've redeemed it already (i.e., if the $100 was credited to your Apple ID) then you can check your account if there's an expiry date for the credited amount - if there is no expiry date, then you can use your $100 for anything you'd like to buy from iTunes later on.
