This book arrived with a dirty/sticky cover that I had to clean with a damp paper towel (twice) to clean it. Seems like a can of soft drink was sprayed over it. The other 3 books in the order was fine. You shouldn't serve your customers with books in this condition. I will not return it, will only have to wait another 11 days to get another copy. But you should really refund me anyway for 1. Having to touch it 2. Having to clean it.
