Ever grabbed your groceries, only to find a mystery charge on your Walmart receipt? One shopper spotted a $23.99 item she never bought—turns out, self-checkout glitches can sneak in random charges.

A quick glance could save you from paying for stuff you never bought! #MoneyHacks #Walmart #ShoppingTips #Business
