You have little control over businesses transmitting purchase data to Facebook or other data aggregators.

Best you can do is withhold information at time of purchase. Use cash, don't give your email, phone number, etc.

Some businesses are clever and dangle a carrot with the request for PII such as emailing you the receipt or texting you status updates. You will have to learn to be "that guy" and politely refuse, or give bogus information.
