Here are a few shots of how you shop for auto supplies,
gasoline and seat covers.  Vendors are very creative in the ways  they advertise their wares.  Another way is to stand on the side of the road and hold what they are selling up to your car window, especially things like windshield wipers, and they shake them to get your attention

This gas station is American owned, we have been told.  We buy gas for our truck and our generator at stations like this.

We pass this vendor all the time - it is a young man who sits on his chair and watches the traffic and waits patiently for an interested customer.
