Why do people buy milk or bread or cereal or soda at the gas station convenience store when those items are far less expensive at a grocery store? Obviously, they have a need for the items. More importantly, buying at the convenience store is quick, and you guessed it, convenient. And "quick" and "convenient" represent value. They fill up with gas, run in and pick up the items they need, and they're on their way. No hunting for a parking space. No grocery carts to dodge. No long checkout lines.
