If you bought Sudafed or another product with pseudoephedrine that they keep behind the counter, a lot of places (if not all) card you. If you watched Breaking Bad you might recognize if as a main ingredient in meth and there are legal limits in how much you can buy. Also, they probably aren’t just carding you, but also tracking your purchases. I don’t think you can buy that stuff online.

(I have sinus issues and used to buy Sudafed until a ENT told me years ago it does more harm than good and gave me an Rx for Singulair, which works much better and is covered by insurance.)
