If they know more about you they can show you one at the top of your price range. Or maybe they know you like to finance things and they can show you a monthly payment. They could also show you one that happens to be your favorite color. Or if they know your political affiliation they can show you the limited "MAGA" model.
Nah I'm good, if I'm looking for "MAGA-themed pressure cooker" just show me a good one, I can refine my query myself and avoid giving you my SSN and bank details.
