How did advertisers know what I bought at the store yesterday?

I don’t use any social media or shopping apps. I went to the store yesterday and bought a particular item. Today I see ads for that item when I’ve never seen ads for that item before. how exactly my phone is letting advertisers know what I bought?

Location data puts you at the store. Existing data about you provides a pretty good guess as to what you might be interested in there. They might not know whether you bought anything, so they’ll present the ad in the hopes that you haven’t and could be persuaded to.
