An Idaho woman says she’s been banned for life from not one, but all Walmart stores in the U.S., after an argument over coupons.

April Cuervas told her local TV station that she was banned earlier this month after asking a store manager to explain the changes in the company’s ad match guarantee, which allows customers to get lower prices at Walmart by providing proof of a better deal at a competitor store.

Cuervas said she decided to record the exchange on her iPhone.

The interaction quickly became heated, she told KTRV Fox 12, and the manager slapped her hand away and told her to pay full price for her groceries or leave.
