This might well be the creepiest #Google page ever: All the purchases a user has ever done. If the user receives a confirmation email for a purchase they made, the user is not notified that Google collected and displays this piece of information in this page. There is no explanation why they are collecting all the purchases in one page, and apparently there is no way to opt out of this or even delete the purchases from the list.
@crazypedia I noticed that PayPal thing, and it's kind of weird. I think that the reason PayPal transactions are not included is that they can be used for donations and simple money transfers as well, so they would fall out of Google's interest. But this is just a conjecture.
About that “only you can see your purchases”… On the one hand, we are used to hear lies like that. On the other, big companies' legal departments tend to be very careful about the words being used. So – I dunno *shrug*
