The unwanted parcel.

I ordered a set of books from Book people which duly arrived. However it was accompanied by a oOsecond parcel, addressed to me and containing three copies of a book which I had certainly not ordered
but had been charged to me. After a long conversation with a very helpful Offi. I was sent a prepaid label so I could post back the parcel .This means I have to take the bus to get to the Post
