If you have a family then there's a good chance you go through them really fast. Imagine making 2-egg omelets for a family of 4. That's 8 eggs right there. Then you bake something with the kids in the afternoon and that's 8 eggs. Then you decide to make pasta for a change and that's 8 more eggs. It's not that difficult to go through a lot of eggs and why places like Costco sell eggs in 2-dozen quantities as well.

It's not difficult to go through 4 dozen a week and at $5 more per dozen that's $20/week and $80/month more for eggs. That starts to hit a lot of people's budgets.
