Very well reviewed American Fridge Freezer. High storage capacity for the price. No water/ice dispenser but you do get more storage space in return. In addition, there is a twist ice box to provide an easy way of making ice cubes.
£399 by using voucher code 'DECEMBER30'. Delivery from free.
EDIT: the initial deal was at £369. However it appears that the price has since been increased. Previous price was £499.
Installation would be extra from £3.99 to unpack to £24.99 for full installation and demo.
