Looking for 4x3 egg cartons at a reasonable price.

[NartkersEggs]

I have found these from www.eggcartons.com but for a few hundred they are .70 cents each. When you only get $4 give or take for a dozen eggs it makes them cost prohibitive. I want the vintage look, I havse 40 chickens and sell what we don't use. I don't need huge quantities. Any good sources out there? Thanks a bunch!
