And when gas prices rise, so does the price of food. When it costs more to transport groceries, you'll pay more to get them.
The severe drought in the midwest last summer caused a shortage in supply of staple ingredients like soybeans and corn. Corn is used to create ethanol and is necessary in expensive animal feeds. So food items from milk to oil to cereal are more expensive.
So what's a Krazy Couponer to do? Build and utilize a stockpile! If you stock up when sales and coupons hit rock bottom prices, you'll pay less because you'll have product on hand when prices increase. A stockpile also reduces frequent trips to the store for last-minute ingredients, saving you time and gas.
Also remember to take advantage of fuel rewards! Many stores offer discounts on fuel when you spend a certain amount in-store with a loyalty card. Do your shopping at these stores, and save at the pump.
