[WhyCause]

It's not necessarily wealth that governs price changes, but access. Anyone with a car and 'enough' money for gas can go to the store across town if it's cheaper, but if a store is isolated enough by geography or neighborhood income level, you'll likely see higher prices.

Case in point: the Kroger in Oxford Ohio (where Miami of Ohio's campus is located) has had remarkably higher prices than other Krogers in the area for as long as I've known. Oxford is 'close' to Cincinnati, but there's enough corn and soybean fields between the two to make the trip a pain.
