Marshall Ward have the Samsung U800, dubbed the Samsung U800 Soulb (or "Soul B") on o2 pay as you go for just £99. It's the non-sliding version of the Samsung Soul, and is at least £150 elsewhere, often £200!! This is a ridiculous price.
There's a few discount vouchers available which might work, including free delivery and also "£30 off a £60 spend for new customers only". Check out the HUKD voucher section. Marshall Ward vouchers don't always work, but this phone is amazingly cheap without them - in fact if the vouchers DID work then the price would be, quite frankly, silly!! QuidCo is also available at 6%.
The Samsung U800 (also known as Soul b) is, in some ways, similar to the Nokia 6500 classic. Not only is it visually similar but it's specifications are similar too. Encased all in metal and just 9.9mm thick the new Samsumg U800 is an impressive looking phone. It has a 3 megapixel camera plus a VGA video call camera. There's HSDPA for high speed data downloads, stereo Bluetooth, an FM radio, HTML web browser, document viewer and media player.
