I have vowed that this year I'm going to use a private profile for Christmas shopping, but the problem is that once I actually buy the present, that's going to be tied into their database whether I use a private session or not.
And since they love to show you ads for things you just purchased, which makes no sense to me at all, then I have to hide my browser windows from that person until December 25th or they'll be able to tell what I got them by looking at the right margin of any page I'm visiting.
