I have not found a printed policy. I have gone to two different Brookshires. At the first one, the cashier stated they don't take them. I proceeded to tell her to take the items off. She called the manager over to void the items. The manager looked at the coupons and made the decision to take them. There were 3 IP's.
At the second Brookshires, the cashier took the 1 IP coupon to her supervisor to look at and the supervisor said it was OK.
I would tell your mom to talk to the supervisor before shopping to avoid the hassle at the register.
That is great that you are helping her out.
