Mr Price says load shedding over the full financial year ended 1 April 2023 cost it an estimated 318,000 trading hours, worth roughly R1 billion in revenue.
Mr Price is rolling out backup power to its stores - but higher stages of load shedding are making life difficult.
Retail group Mr Price has warned of increased cost pressures for the rest of 2022, with consumers expected to remain under financial strain as the cost of living increases.
