A+ for O'Reilly Customer Service: Keep the books and donate them

The other day while placing an order through O'Reilly, I inadvertently submitted two orders. When I caught the mistake, O'Reilly had already shipped two identical orders to me. They gave me a full refund, however, instead of making me ship the books back to them the told me to just go ahead and donate them to a school or library. Donating books is way more fun than a trip to USPS.
