They did that here too. I refuse to use them. Do they lower the price if you use self serve checkout? No. So, in effect you are paying the store for you to do the work for them. Part of the price of the goods is the wages of the checkout clerk and the bagger. If you do that work and the cost does not change, that is extra profit for the store that they have not earned.
I ain't that stupid.
I guess it never occurred to you that they may reduce the markup on their prices, especially in such a competitive enviroment as food distribution is in the US.
Oh, that's right you probably think that the old Soviet model for food distribution is ideal.
Never mind.
