They dont produce chaper good for black friday They mostly sell for a loss on Black Friday to attract people and generate other sales because those cheaper items are loss leaders . They don ' t Produce cheaper versions of the same goods I have never seen that . Also it is paying for brand awareness . For example McDonald ' s on Las Vegas strip doesn ' t turn a profit . Its pretty danm hard to turn a profit paying 1 mil a month rent selling 5 $ cheeseburgers , but its great for your brand because it make McDonalds seem nice , not cheap , meaning higher sales elsewhere . Likewise selling Sumsung TVs for cheap and having people fight over them doesn ' t turn a profit , but its great for the brand meaning higher sales elsewhere .
