I sell eggs casually when I've got a few extra dozens. I have depleted what was once a huge stack of empty cartons donated by friends and neighbors. The people who buy them at our roadside never return them, so now I need more. I called one local feed store and they sell 200 for $59.00 or .33 each. So I called another local feed store and they don't sell them. They give 'em away. Apparently locals drop off their empties there and they just give them away. It pays to call around, eh?
