Walmart here, 5 bucks a dozen in the 5 dozen box (which I don't buy, because of bad experiences with broken eggs and even one in which the 'white' was pink--a sign of bacterial infection in the egg).
One of the local grocers has 18 count eggs at roughly 7 dollars, which comes out cheaper than the high by almost 4 bucks, and comes in at a shade below $5 per dozen. The added benefit is that I can check fro breakage or nasty cracks before I buy them.
