Shopping at the grocery store isn't always a walk in the park. You're bombarded with offers that seem to be a bargain -- but could just be a bust.

As an example, let's look at two end-of-aisle advertised specials on sale at two different grocery stores. For the sake of argument, let's say you have cream cheese on your list. At Store A, you find you can buy 10 packages of cream cheese for $10. At Store Z, cream cheese is advertised for $1.29 a package -- the fine print says you don't have to buy 10 packages to get the special price. Given these choices, you should shop at Store A, right?

Maybe not.
