As a consumer:
I pay $6-7 dollars for a dozen 'pasture raised' eggs at the grocery. :/
Organic labeling in grocery means nothing to me, as it can mean that the chickens still eat 100% corn. If your chickens are pastured, advertise that as it really places your eggs above all those meaningless labels at the grocery, where the factory farmed eggs are $2-3 a dozen(organic, free rage, cage free-it all means corn fed to me).
Convenience is key-there are awesome eggs at farmers market, but I cannot make it there every saturday. I have a friend that has beautiful eggs but we need to coordinate our schedules better. And this is why I buy the pricey store eggs(that lack in quality too) and am going to raise chickens(price and convenience).
I love the idea of bringing your own carrier for a discount.
Good luck!
