Under escheat doctrine, your state government might be holding past paystubs, refunds, rebates, etc. that they couldn't deliver to you for one reason or another. "Unclaimed property" in other terms.
You should be able to search for free and file a claim for this withheld money based on name and address of residence/delivery.
I just searched for my name, and while I came up with nothing, there IS antoher Brian Choi who is owed like $320 USD by NBC Universal in the same city.
