$4, for "organically Raised-free ranged eggs" here in MA.
BUT do NOT put ORGANIC on your eggs UNLESS you are CERT ORGANIC.
It still depends on where you are located, even in MA there is a big range.
I had one guy in my town that I shot an email to when I had extra and I even delivered to him (1 mile away). The carton I used was a bottom tray.
My daughter just gave 6 eggs to her Foods teacher, who may buy. If she does I am not sure what to sell for, probably $4 but I have to check Whole Foods to see what they sell for and price accordingly
