Even though Apple reported 15% lower revenue from iPhone sales during its fiscal first quarter, it still ended up with a net cash balance of $130 billion at the end of the three month period. So the company can afford a new promotion that adds a 10% bonus on funds you deposit in your Apple ID account. According to MacRumors, the promotion will end on March 14th.
The money in your Apple ID account is used to purchase paid apps, buy content on iTunes, and purchase storage space on iCloud. The 10% will be applied on deposits ranging from $1 to $200 which means that the most Apple will fork over in bonus dollars to one customer is $20. The promotion is also offered in Germany, although in that country Apple is giving customers a 15% bonus.
To deposit funds into your Apple ID account, go to Settings > iTunes & App Store > Apple ID > Add Funds to Apple ID. That should take you to a page that gives you the option of adding $10 (+ $1 bonus), $25 (+ $2.50 bonus), $50 (+$5 bonus), $100 ($10 bonus) and $200 (+$20 bonus). You'll also find these options when you scroll to the bottom of the App Store and tap on "Add Funds." To take advantage of Apple's largesse, you need to have a valid credit or debit card attached to your Apple ID account.
