Supermarket Advertising

Each week I go food shopping at Stew Lenords. Since im learing about advertising I noticed that they advertise some of their products while driving up to the top of the hill. They advertise products such as Lobster Rolls for 7.99, Chicken Salad for 5.99, Milk 2.99, Cheese 3.99. I like that they advertise along the side and having photos of the product too, so you see a good deal before you get inside the store.
