Our local store only give a couple of extra days.
One thing to note, if during a Kohls cash earning period you shop a couple of time you can go to customer service and get your receipts combined. So, if you need to spend $50 to earn Kohls cash and 1 trip you spent $35 and the next trip in the earning period you spent $25, take the receipts to customer service and ask for them to be combined so you can get your $10 kohls cash.
