General Collateral Financing Trades - GCF
  
You're looking to purchase a camper or RV for weekend road trips. As you work with the banker and are discussing a down payment, or some other source of collateral, you give the banker a couple of bonds your grandparents purchased for you. Once the banker confirms the bonds are still active and current, he allows you to use them to purchase your camper or RV.
The bond works just as well as a cash payment, but a little more quickly. You will still need to sign a boatload of paperwork, but you're about to prove you are able to pay for the loan, and bring the original cost down by using the bond.
