Apple has launched a promo that rewards Apple users an extra 10% bonus in iTunes credit when they load up their Apple ID account. The bonus applies when you add anywhere between $1 to $200, with a max credit of $20.
To add funds to your Apple ID via linked credit or debit card, you must first go to the App Store, then locate and tap your profile photo. The option ‘Add Funds to Apple ID’ comes up- tap it and you’ll be taken to a screen to select the amount. Tap next and confirm with Face or Touch ID and voila! you’ll see the bonus on iTunes.

iTunes credits may be used towards purchasing books, apps, iTunes shows and movies, for subscription fees, Apple Music, Apple Arcade and more.
The promo began in November and will be available until December 12. You can get maximum savings by combining Black Friday and iTunes deals.
