There are very few aspects of life that aren't directly affected by the price of oil.
Directly affected are manufactures that require oil as a raw material, such as plastics. Obviously as the price of oil goes up, so does the price of those manufactured goods.
Indirectly affected are goods that have to be transported. Every train, truck, cargo ship and airplane needs fuel, and currently our fuel source is primarily oil based. The longer it has to travel, the more it gets hit by the rising costs of fuel... so even if you don't drive to the store, your milk, bread and cheese DOES. You'll be paying more.
Additionally, on the topic of food preparation, most of the food grown in the world depends heavily on automation (for tractors, combines, etc) and all those automations are run petrochemically. Thus, oil price increases do a double-whammy on agriculture.
There's far more than this, of course... suffice it to say that an increase in oil prices will permeate every aspect of your daily life (assuming you live in a 1st world country where people don't still cultivate rice by hand and in bare feet).
