Like most things, eggs are cheaper in bulk, so the unit price of eggs is better for the big 2 1/2 dozen cartons. But of course it’s a pain to buy that big pallet of eggs, it takes up so much room in the fridge! I’ve started just transferring the eggs to regular cartons, which are so much handier! I just save a 12 egg carton and an 18 egg carton and those are the perfect number for the 2 1/2 dozen egg pallet I buy. The smaller cartons stack nicely and I feel like they offer more protection for the eggs.
