Even worse when you consider this is without tax and the compareisons are made to prices without tax. To be fair the rest of the world doesn't threat their eggs so they need to be refrigerated like these US eggs need to be, which also costs money.
In my state, prepared foods are generally taxed while produce, canned goods, dairy, and many others are not. The system is confusing enough that hardly anyone knows what's taxable or not, so they rely on the store systems to do it for them.
