The Walmart store charges some special fees for loading cash app accounts. You need to contact the cashier of the Walmart store and give it your account details and the money you want to add. He will add money and take some amount like if your balance is in the thousands, then he will charge around 100 – 200. If your amount is less, there may be a lower fee. If you ask the cashier to add money to your Cash app after closing the Walmart store at time 4, it will charge extra money for this purpose.
