Kindle books

I received a kindle for Christmas this year and I love it! I have downloaded several books that I have been wanting to read for a while and most seem to be cheaper then the paperbacks which is good. I have also been looking around on Amazon for as many cheap (49p- £5) or free books as I can find.

The site above is one I found that announces when ever a book becomes free or drastically reduced in price. It's pretty cool actually, the only problem is it is for the US only. So I was wondering...does any one know of a similar site for the UK? Also if you come across I great bargain would you please post it here for all to see?
