I went to Whittards yesterday, they had 50 shades of Earl Grey :?
I flicked through a PDF of it earlier (if you can flick through a document on-screen) - both me and my girlfriend thought it was rubbish. It's very badly written for starters, as shown in this blog post and Private Eye a few months ago before copies became visible on every Tube carriage. It's not worth paying for!
Also, it's a sign of the ubiquity of the books that we're even talking about them on here!
