I routinely go to my Amazon page, where I sell my fiction, to check for any new reviews and other postings.
I usually get ads sent to my email within 3 days - to buy my own books. It would seem the Amazon computer has yet to recognize my email addr is the same as the ‘author’s”.
Gotta love silicon....
When I search on say cameras I start seeing camera ads everywhere. You could delete the cookies but with Amazon they have your search history and sell it so you are tracked by them and others.
