This website may put some cash in your pocket, or in the pockets of people you know.
This is an omnibus website for unclaimed funds left in old savings accounts, insurance rebates, IRS overpayments, etc.
You choose your state, then you can do the search in the state database for your state. Do the state search, not the 'missing money' one, it's much more complete. It's fun sometimes to go and see who you know who might be owed some money. It's a fun gift to be able to tell them they might have $100 coming from an old checking account. It's completely free! I do this maybe twice a year and have found several thousand dollars for others over the years. Give it a look.
