In my area (suburban Detroit), the Whole Foods Market is carrying certified pasture raised eggs for $7 a dozen. Then again, a friend of mine sells hers for $4 a dozen (in recycled paper cartons) OR there is an online site where local farmers sell CSA and family farm (organic) leftovers, and those pasture raised eggs go for $6 a dozen, delivered to a store near my house. My first stop is my friend's house, as I KNOW her, love to support her, know her chickens and what they eat and where they run around. My next stop is the website from local farmers. I'll pay a buck less to spend less gas than to go to Whole Foods! Lastly, if I am desperate and it's the middle of winter here, I will cross my fingers and hope the Whole Foods birds are laying. It's REALLY hard to choke down $7 a dozen, but then again, once I had real eggs, it's hard to go back to commercial ones. I would actually prefer to just not eat eggs till laying season starts again!
BUT, I have just moved to a little five + acre farm with a barn and a coop, and have chickens coming, both from a friend, and some that I ordered. I have a feeling that in the summer I'll have more eggs than I can use, and then some! I'm thinking $4 a dozen sounds good, as my friend who sells her eggs seems to do well with that cost... I will see what the market can bear!
...my husband works in a less rural area, and I am thinking that that "put it on the desk in a clear carton" idea is an AWESOME one!
