Where can i get cardboard egg flats?

[MarkS]

I forgot to mention, are there any type of retail stores that carry cardboard egg flats? I like not having to pay shipping, and it's nice to shop around for best prices.

Thanks for the links flameethrower!

ULINE has them

Shipping is pretty cheap for me since they are located in Eagan MN, you may even be able to pick them up in person
