The Cash Card is a debit card that allows regular users of the Cash App to use their current balance at stores that accept Visa, instead of deducting money from their bank account.
Again, I have got good news for you. And that is, you definitely can add money to Cash App card at Dollar General store. And to do so, all you have to do is just approach the cashier at the billing store with your cash card. Tell him that you want to load your Cash App card with money. Then, simply verify your number and give your card to him/her. Further, within a few seconds, the cashier will give you back your card with freshly loaded money.
