The prices of popular grocery items can vary widely depending on the region or on the store. Generally speaking, over the past year, prices for many grocery items have grown slightly, due to inflation and increased demand for certain items. For instance, a gallon of milk could have risen by about 5% with the current national average at $2.99. Similarly, a dozen large eggs may have grown by 5-10%, with the average price at $3.24. Prices of vegetables and fruit will likely depend on the season and region. However, staples such as apples and potatoes may have increased slightly as well. The price of meat can also vary greatly, but the national average for a pound of sirloin steak could be around $7.22.
