Aaron Brown's new book "The Poker Face of Wall Street" had been getting good reviews on Amazon amongst others

so I thought I would place an order. When I ordered it the book was priced at £14.11, so in order to qualify for free shipping I ordered some rechargeable batteries

They were priced at £4.79. However, what I didn't realise until checkout was that they were from a third party so would not qualify for the free postage. I didn't have time to go through the process again so completed the order.
The batteries hadn't turned up until this morning so I checked the order - the postage on the batteries alone was £4.50 (for 4 triple A batteries!!). After further investigation I found Amazon selling them for £5.82 - this would have qualified for free shipping. If I were Amazon I would rate prices with P&P included.
To further annoy me, the above book's price was slashed in half - I hope it's a good read!!
