In Joey's scenario they are not paid for because the customer's "EBT
card balance" was less than the "Food Stamp Total" portion of the
transaction, that is why it was rejected. After the EBT rejection, have
you tried hitting Clear then Total, then voiding off some Food Stamp
items? The "15 Signon" is a good way to help the cashier and customer
determine which items to void to get within the card balance.
