Yes, absolutely recommend. I have bought from Amazon for several years, they are brilliant. You order on Monday and more often that not it arrives on Wednesday morning.
Totally reliable and fast, and I don't work for them!
Another great one is Play.com, in fact i use hem more (free postage) but Amazon is great. Register in amazon.co.uk and you also automatically can use amazon.com (US version)
Bare in mind that sometimes you might not be buying from Amazon, but from a seller operating a shop through Amazon (much as happens with ebay). When this happens, the Amazon website makes it clear exactly who you are buying from.
As with others, I have had no problems buying from Amazon (whether direct or from an intermediary seller) � some bargains to be had, even when you include p&p.
I've bought stuff off amazon for years, never ever had any problems, definitely recommend. Also as previously mentioned I would recommend play.com esp. for books, dvds, cds etc
