No, no, Apple is not stealing your money through its online music store. Rather, it turns out that thieves are beginning to use online services in this case, iTunes, to test the legitimacy of stolen credit/debit cards. It works in three stages. First, the thieve steals your (or some unlucky person's) credit/debit card details over the internet. Then, they make a small purchase through iTunes. Since the value of purchase is usually less than $10, little or no warning is given to the cardholder.
Once the iTunes purchase is successful, the thieves then use it to purchase more expensive items. Remember to check your credit/debit card statements often, and always be alert on the internet.
