Humbug. While the outlets are cheaper than the breakers, it
depends on how the house is wired as to what would be best.
I have just one protected breaker which serves all of the
outlets required to have such protection in my house. If
you have several circuits that need protection, then a
protected outlet (first in line) would likely be cheapest.

You have one breaker for your kitchen, all of your bathrooms and your
outside outlets?
