You can reuse the cartons, unless soiled...I have had friends collecting their old ones for me for over a year..
you could put a personalized label on them with say, a name of your "company", like Egg Farms, or whatever cute name you come up with, and maybe
a couple instructions, "wash before using", maybe tell them it takes longer to boil a fresh egg, ( 12 min actually)
You COULD buy them, but why...some people give discounts, 25 cents, whatever, to customers who return the carton for more.
I live in Southern Colorado, I am going to start at $2.00 a dozen, I have heard in some areas, in NY for example, $7.00....
People will pay what you ask usually, if they know what they are getting, but check around, see what the grocery store sells free range, cage free eggs, and base it off what your
customers say...
I don't want to get rich, I want to be able to at least buy more feed...and of course supply family and friends with great eggs!
