it is typical. that being said, when i was vacationing in florida, i bought a mariner's compass book - $24.99. when i got back to the cottage, i realized that the compasses were 3D, not at all what i thought they were. i called immediately and explained. they checked while i was on the phone. luckily, i had charged it, so there was a record. they agreed to take it back the next morning because i called so promptly. they knew i couldn't have copied so fast.
but she did explain that they have a policy of not accepting returns on books for copyright reasons. i just lucked out that time.
