As of 2014, the standard price for non-organic eggs being sold in a supermarket in the United States is $2 per dozen. This may vary slightly by state, but as of this date, it is considered the average rate.
Prices increase if you choose to buy organic eggs. Free-range, organic-fed hen eggs cost about $5 if you purchase them directly from the farmer or from a local farmer's market.
Many people continue to be satisfied with store-bought eggs, as they are inexpensive and easily accessible. Free-range, organic farmers tend to have more overhead to their supplies, hence the higher pay for those eggs.
