The Walmart self-checkout near me doesn't use the weight sensors, they're turned off. It makes checking out much easier. Also, they flow better, for instance, at Lowe's, you need to specifically press the "Pay Now" button to pay, but at Walmart you can just shove your card in when you're done scanning, and it starts the checkout process. At Lowe's you must choose between the print or email receipt, but at Walmart you can let the question time-out while you put the groceries back in the cart, and it will print the receipt. The Smith's self-checkout is even more clunky, and very chatty. I don't like it.

There are plenty of reasons to hate Walmart, but IMO, their self-checkout works better than the others I've tried.
