Sam's Club is opening a location in Dallas that will allow customers to scan and pay for their groceries with an app — without a cashier or standing in the checkout line.

It comes at a time when many retailers, including Walmart (which owns Sam's Club), Target, Kroger and Macy's, are playing with technology in stores to appeal to customers, cut costs and grow sales. The opening also comes in a market ripe with competition in the grocery industry — Whole Foods is headquartered in Austin, Texas, with H-E-B being another popular, local option.
