Know your bins,swipe card and walk out with your shot. Or are you talking about copying a upc barcode off a cheaper item and printing that upc barcode on your high dollars iten and taking it thru self check out or the outdoor center.? Thats been done for years and is now obsolete. Unless there is a cop out side waiting because of an unrelated incident. the greeters have been to not to confront people leaving their stores and they cant touch you ever. I saw a guy push a cart full of steak and chickens and nobody did anthing to stop him
