Welcome to the site, LittleLou!
Tesco have done this before.
My local branch put 'A Hat Full of Sky' on the shelves a whole two weeks before they should have. I managed to grab a copy before anyone noticed.
On the message board I was then posting on, one of the members had a book store in America and she had a proof copy. The two of us were the only two people on that board who had read it and so we started to write to each other about the book. A couple of years later we got married.
I don't know whether to thank Terry or Tescos for that.
Look, you've got it all wrong! You don't NEED to follow ME, You don't NEED to follow ANYBODY! You've got to think for your selves! You're ALL individuals!
Yes! We're all individuals!
