Free money is never a bad incentive towards anything.
Up until March 14th, Apple is giving users a 10 percent bonus credit when they transfer money through their credit or debit card to their account.
Users can add money to their accounts if they dig into their phone’s settings: you first must go into settings, then to iTunes & App Store. From there, you click on your Apple ID, and then View Apple ID. Finally, on that screen, you can click on Add Funds to Apple ID, which announces the bonus, and shows you what your balance is. Adding $10 will get you an extra dollar. Adding $100 nets you an additional $10, with the limit being $200. Clicking on one of the options will prompt you to pay with Touch ID.
The feature is also available for desktop versions of iTunes as well. Here, users can go to the Account menu, click “View My Account,” then click the option to add funds. Clicking on any of the options will automatically add money to your account without a confirmation, whereas on your phone, you have the added step of hitting Touch ID or entering a password.
Unfortunately, this is a one time thing, as the action can only be performed once, per the fine print. Users can still add money to their accounts, although the bonus won’t happen again after the first time.
