I know the way "Sam's Club" items used to be made and I would think that Walmart items would be the same. But it is just a guess. They approach mfgs. for a quote on an item that they want to sell. They give the price point, features and what they want to pay for the item. They then say they will move x amount of items over x amount of time. So mfgs. will "make" and item for that purpose and you get what you get. After buying a printer at Walmart, I did find out that it was made only for Walmart after I had problems with it. I took it back. Seems that when mfgs. are trying to win a bid, they will use cheaper components just to make the sale.
