this has happened twice in two weeks last week my wife bought corndogs out of frozen center checked date they were indate went to cook and they had mold unfortunately receipt was lost,this week she bought great value fish fillets indate these were moldy and green in middle again we didn't keep receipt,this tells me several things either employees are finding food products in other part of store and returning them save your receipwhich should never be allowed,or its happening at checkout when a person decides they don't want it in either case our money comes hard and we have a large family to feed save your receipts and I really think management should look into this asap,food products that have been left out in the store exspecially freezer products shoul never be reshelfed sincerely a very concerned customer.
