I have never used Mr Porter, but I have found other businesses in the Net-a-Porter group to be extremely fair, accurate and prompt with awards. I have had one clawback when I attempted to stack the eStore with and American Express cash back which, again, was fair enough and in accordance with the T&Cs. The current offer says, "You will earn a lower reward on purchases that include luxury watches, sale items and selected sneakers." - I doubt if £40 would cover a luxury watch but maybe it was a sale item?
