How about the Repurchase Agreement for the Advertisment Credits?
Together with the Purchase Order, on your letterhead, New Chances will provide a Repurchase Agreement, offering to buy back from you the Advertising Credits you bought, and pay for them 4x the value you paid for them.
Once the money is available to do that, the product you ordered will be delivered to you at no cost to you.
