YOu can add money to your Cash App account via a credit card, debit card, or bank account that you link to the account.

In addition -- and I haven't used this yet so confirm everything I'm saying -- you can also get a Cash App "Cash Card" which is basically a Cash App Visa Card linked to your Cash App account. You can go into big retail stores like Walmart, add cash directly to the Cash Card, and that shows as available balance through the CashApp app. 'course, if you're worried about the wife seeing all this, you have the problem of explaining the Cash Card that was mailed to your house. But if you can get past that, then basically you can go to Walmart, take $300 out of the ATM, walk over to the counter and put that $300 on your Cash App, and all transactions only take place on your Cash App account
