Which Android app should I use to skip checkout lines at a warehouse store?

Sam’s Club is a comprehensive mobile tool for members of the warehouse club, with its flagship feature being Scan & Go. This functionality allows shoppers to use their Android phone's camera to scan item barcodes while filling their cart. Payment is handled securely within the app, generating a digital receipt. Upon completion, users simply show the e-receipt to a greeter at the exit, eliminating the need to wait in a checkout line. This is particularly useful for quick trips, busy parents, or anyone looking to minimize contact and save time. The app also supports curbside pickup orders and allows users to manage their membership details. However, some Android users have reported occasional glitches with the final transaction code, suggesting the experience isn't flawless on all devices. Reviews indicate high satisfaction with the time-saving aspect, with one user noting, 'I'm also a huge fan of Scan and Go!' The app effectively turns a smartphone into a self-checkout terminal, streamlining the in-warehouse shopping process significantly.
