By the way, when I was done with the first Sally Lockhart book, I quickly went online to order the last three. Each costs eight bucks on Amazon. When I went to check out, I was surprised that $24 doesn't merit free shipping. The minimum is $25. So I Decided I'd add another book for the price of shipping and a little more. But, Amazon was running a 4 for 3 deal, so not only did I get free shipping, I also got a free book, and because of another phantom discount I wound up paying only $23 dollars for the whole bundle.
