The Prdoukt was "very good" offered with the feature and therefore purchased from me.
However, the book received is at most the term "acceptable". Cut edges are yellowed and stained, back has strong kinks, cover corners bulge out, the whole book is heavily warped. The pages feel "greasy", so that one feels the need to have to wash every time after reading the hands.
Since I had read the material for an English Studies Seminar, I have willy-nilly put the book in this poor condition on a trip and could not return it immediately. What I would like to do but now, when I get a better copy it.
In no case the book is the price paid value! Especially since it is excellent as a factory price with only 6.99 BPD.
I expect solutions
