Now you can pay £49 for something that many other sites offer as part of their standard service for free. Just what I've always wanted!
Amazon is good for books but it's still cheaper to buy them from the US with the exchange rate and pay the extra delivery because there's no import duties on books. Games and DVDs etc. are sometimes decent their if you buy through the Amazon marketplace but they usually charge £2 postage and aren't covered by this and most their other items tend to be large one off buys - not something that's covered by this or that you would buy regularly enough to justify it.
It's still best to get games and hardware etc. from places like shopto.net at the end of the day who undercut from anything between £5 and £20 on games and offer free next day delivery.
