For those of you who are impatient like me, Sam's Club has a new app called Scan & Go that allows you to scan all the products as you put them into your cart and skip the checkout lanes. You just show them your receipt on your phone as you walk out the door. We've used it a couple times and it works like a charm. It takes just a couple minutes to set up the payment options on the app and it lets you use any major credit card, Amex, Visa, Discover, Mastercard.
