Whilst I've not bought from UK Digital Cameras before and can't comment on their services, they do appear to have excellent price match and returns policies. Looking for the best price on this Sony CyberShot H2 with a 6 MegaPixel Resolution and 12x Optical Zoom, it comes up at £209.99 and delivery starts at less than £5 for 1-3 day Citylink. I think this is a great looking camera and reviews are good too.
14 day return policy and free two year warranty on all digital cameras, as well as price matching.
