Anyone tried Paradies new book return program? I love this new program.

If you buy a book in the Paradies shops which are in many airports, you can return the book at another Paradies Shop and receive 50% of your purchase price back. Last week I bought a new Mary Higgins Clark hardback (which I would normally buy at Costco rather than pay full price..). Was finished with it by the end of my trip, so I returned it to the Paradies store before heading home.
