"The value of books... because cheese and crackers never changed anyone's life: When people get yet another basket filled with fruit or wine or cheese and crackers--it is hard to remember who sent what--but when they receive a book or a basket of books or a series of business, current events or history books--it feels thoughtful and personal and memorable. It also represents lots of value--hard to imagine what would have as much impact for an expenditure of $30 or $50."--An e-mail newsletter sent by Roxanne Coady, owner of R.J. Julia Booksellers, Madison, Conn., promoted "Corporate Gift Ideas."
