Very interesting. I haven't found Amazon UK particularly 'cheap' for the past couple of years at least, usually their day-to-day prices are about the same as mainstream and sometimes rise quite markedly for short periods. Their primary advantage here seems to be centralised shopping and convenience of payment. An example was a book on which they were offering 3 pence discount on the RRP. Hardly worth bothering about, but very low friction to buy from them instead of another site offering £1 off because my payment and delivery details are already lodged with Amazon.
