Where's the cheapest place to order egg crates?

I'm looking for some new egg crates for my roach colony. Where have you found to be the best/cheapest place to order them?

I personally don't order them. I just go to local store that uses lots of eggs, like diners, bodegas and what not. I just ask them to hold some for me while I'm in there and pick them up a day later. If it's free it's for me! :-)

Buy a dozen eggs, eat the eggs, then voila you have egg crate lol...

I just got a bunch of them through a mexican restaurant. The day after I put the new crates in the tub it smells like something died my roaches are fine though. It's the egg crates, I have no idea what's wrong with the crates but it's nasty. I figure I'd just buy some from here on out instead. Maybe I should try to get some different ones and see if it was something weird. :confused:

Internet and your local feed store/del's farm supply/tractor supply co will have them cheap.
