My creepiest experience was shopping at Lowe's and then getting recommendations on Amazon that night for drill bits and cabinet door handles. The thing is, I had purchased some drill bits at Lowe's so OK, but I had only stopped and looked at the cabinet door handles.
Your phone told advertisers you were located at Lowe's using GPS. Then your credit card company told advertisers you bought drill bits. If you looked up any cabinet door handles in the past, that data was given to advertisers too. They put all those pieces together to serve you more ads on drill bits and cabinet door handles.
A lot of stores keep track of which aisles you spend more time in, that information is then shared with their "partners" (ad networks). By the time you made it home, they had already shared that you bought bits and that your device spent a while looking at cabinet hardware.

I'm sure there's more than a little Baader-Meinhof happening. I did expand my privacy a bit; pihole, searxng, some other stuff and I notice it less now. Or I think I do, humans are notoriously bad at this.
