Waterstone's, one of the largest high street booksellers in the UK, is a relative newcomer on the block. It first opened in Old Brompton Road, London, in 1982 and now its flagship store resides at what used to be Simpson’s of Piccadilly - the iconic menswear department store. It’s winning formula is the 3 for 2 offers, endless supply of current pulp fiction and the sheer mass of books on the miles of shelves. It’s a formula that has the purists - and plenty of authors - shaking their heads and, in extreme cases, inciting boycotts. With more than 300 stores on our high streets it is difficult to avoid this giant. However when you want to pop in for a beach read, to stock up on your university reading list or the latest biography it couldn’t be more comfortable or convenient.
