I had the reverse of this, bought what I thought (and was told) was a boot, decided to sell it and wait for a real un. I had it in my sales box for about 18 months, that well known double act ( with impecable taste) from Manchester realised my mistake and had it away, never lost any money but I had a real one all the time I bet this has happened quite a few times but people dont like admitting it.
