Regular eggs: $2.99 per dozen
Organic eggs: $4.79 per dozen
Buying a dozen organic eggs each week would cost you about $95 more than buying non-organic over the course of a year.
The egg section was particularly difficult to navigate because of the overwhelming choices: cage-free, organic, free-range, natural, or pastured. The cheapest organic dozen I could find were the $4.79 "grade A fresh" eggs, but there were other organic options at $5.69 a dozen, and even $8.69 a dozen for "pasture-raised" organic ones.
While $95 isn't a huge difference over a year, if you opted for the pricey pasture-raised eggs, that would cost you nearly $300 more than sticking with the conventional eggs.
