Office Depot & OfficeMax offers a selection of cleaning products that qualify for 100% back in rewards points. (Not an Office Depot & OfficeMax Rewards member? It's free to sign up.) Points can later be redeemed like cash at Office Depot & OfficeMax, yielding prices that start at $0 after rewards. Shipping adds $9.95, but orders of $9.99 or more qualify for free shipping. (In-store pickup is available on select items.) A five-item limit applies.
