Well I could use some eggs right now.
But, I let people know I sell them and I try to keep the price about 50 cents above the store price.
I also give out literature from publications I find about the health of pasture fed and free range eggs.
My wife sells eggs through work. If there is a bulletin board you can use to that.
You can advertize on Craigs list.
For cartons Egg Carton. com occasionally has "seconds" for cheap. I've yet to use any that I bought, cuz friends save them for me, but they're here If I need them.
You can buy cartons that are easy to split to half dozen, and sell them by the half dozen to folks who don't need alot of eggs.
They make nice gifts to friends who've lost their jobs or are working for less money and need a hand.
Or as someone suggested freeze them.
