That's really cheap for a book that's supposed to be as rare as hen's teeth! Ah, I get it, you are like that 'antiques expert' who came round yesterday, valued that old Michelangelo statue I have in the garden whose arms have broken off at £20, and expected me to sell it to him. "Hardly worth my while driving over to pick it up, guv, especially as it's damaged stock". Only joking....
