Here is one question that people ask frequently. “How much money can I get back at Wal-Mart or CVS stores”. The answer is $10 to $20 but no more than $20. I have never seen more than 20 given back at any store that offers cash back as a convenience. I believe the limit is 20 due to risk or due to the availability of bills.
The stores don’t want to run out of cash. At Wal-Greens I have seen as even $5 being available as a cash back option from Debit-Card.
I believe Target also offers cash back at cashier register but It’s been a while since I visited a Target store, I believe they are also $20 limit.
