If you’re like me, though, you may wonder how much all those one-click purchases add up to. After all, a few clicks here, a few clicks there, and pretty soon we’re talking real money, right? You can view your iTunes Store account’s purchase history in iTunes, but that shows you only 10 items at a time, and the list includes free updates, making it a real hassle to try to add everything up—especially if, like me, you’ve downloaded many, many apps over the past year.  - Dan Frakes, Macworld.com
