Providing you know what you want buying a 'Graded' item is fine and often a bargain as many ovens etc are only slightly re-modelled and given a new number. Kingdoms web site is particularly easy to navigate and they are at pains to describe appliances in detail including any slight defects. The no-quibble ability to reject the appliance on delivery is excellent. In my case I found on delivery that I had ordered the wrong oven. I rejected it and discussed with them an alternative oven that had the features I really wanted. They went out of their way to find me an alternative oven and even reduced the listed price. The only extra I had to pay was the increased cost of the oven and a new delivery charge. Excellent service and communication.
