I totally agree and am sick and fed up of it. I went into a store and saw a lovely handbag. The label stated leather and there was even that funny jigsaw shaped leather sample attached to the bag.
I can smell leather a mile off and knew this was not leather. There was nothing on the label to say it was PU but I found, tucked away behind the zipped pocket, was a very small tag that said PU.
Surely this is false advertising and is illegal especially when the price reflects it should be leather. So many pairs of shoes, purses, jackets state leather when it is PU. I will never buy anything leather I want online as I do need to smell it first.
