When you buy a 600g loaf of whole wheat bread from Ralph's Supermarket at 6:17pm on Tuesday Sep 22 2026 for USD4.99, there is zero (0) reason to consider that any more your data than Ralph's data.
Just as you can use that set of facts plan and optimize your budget, so should Ralph's be able to use that data to plan and optimize their business.
That the company can use the fact that a customer purchased something is completely separate from tying that information to me.
And they should not be able to sell that data to data brokers, whether is anonymized or tied to individual customers.
