http://www.eggboxes.com/Item/13 - direct link, and all made in the USA!
So long as you buy domestic the shipping is free, so that breaks down to:
38.6 cents per egg crate when you buy 70 for $27.00.
32.9 cents per egg crate when you buy 140 for $45.99.
19.0 cents per egg crate when you buy 3,920 for $745.00.
Blasted OCD in effect...<sigh>
Only thing unclear is if these are new or recycled, so I called and these are
ALL 100% NEW. They make them from recycled news paper and form the egg crates themselves in molds, and they are baked which will kill any germs or parasites, so these are perfect. They also have normal egg crates if anybody needs these, and they have some with misprints, which are not faulty, they are just products someone had ordered with specific print on them that either never paid or they lost the account.

This site has good prices too, but I didn't get time to call. They are from Marion, IL 62959.
$0.29/1 egg crate
$5.60/20 egg crates - 28 cents per egg crate
$19.60/70 egg crates - also 28 cents per egg crate
All of their shipping is next day which is $40, but I e-mailed them and they said
"We can absolutely switch an order of just egg crates to ground shipping for you, just give us a call and order over the phone. 800-423-2248" - Andy Petit - Sales Manager.
