Wife uses Amazon, I get FB ad for this product. Spooked

OK, this is going too far.



My wife is German and looks at a watch on the German Amazon site.

Later I log into Facebook on a different computer and get an ad for this same frigging watch, from Amazon.de



What's next? Will FB give my wife sex tips, based on my porn history? (wait, I'm making this sound like a good thing)



I'm not easily spooked by the magic of databases, but I feel this is unpleasant.
