Does the color of the eggs you buy matter?

It does if you're using our common cents grocery store tips.

Parenting.com put together some interesting hidden savings at the grocery store.

First, buy white eggs instead of brown.

Unlike bread and rice, white or brown eggs are equally nutritious.

Also, buy frozen concentrate instead of carton juice and opt for frozen fruit.

You don't have to worry about it going bad before you eat it.

If you can, swap cereal for oatmeal a couple of times a week.

Make sure you buy a container of oatmeal, not the individually packaged kind.

Finally, compare unit costs, not prices.

You want to know how much the product costs per ounce or pound.

Those small changes could save you an estimated fifteen bucks each time you shop!

In a year, you've shaved more than $350 on your grocery bill if you shop twice a month.
