Their point of sale program most likely is using your credit card number, or debit card number, do you have a payment app installed on your phone? It probably connected your online purchases with that payment account number.
Edit: I forgot to add, that when you fill out all of that information online, it's connecting it to in store purchases using that card. I used to be a small scale POS manager for a small chain of health food stores. POS as in point of sale, not the other meaning.
