The Nova Scotia Liquor Corporation says it will both donate $29,891.70 to charity and offer customers a refund after a computer malfunction problem triggered a price increase before it was scheduled.

The liquor corporation said some customers might have been charged more at the till on March 30 than what was advertised on the shelves.

The company said it will "make it right" and donate the full amount it collected to a Nova Scotia charity.

People can vote to donate to the QEII Foundation, MADD Canada, United Way or the Canadian Mental Health Association. Customers can bring in their receipts for a refund.
