has no force in law, and may be seen as an attempt to restrict or deny a consumer's rights. Courts have previously ruled that this phrase is illegal, and you have every right to expect the same redress in law if you buy something from the bargain corner as you would if you bought it off the shelf in the normal way - even though the 'sold as seen' notice is displayed.
If, on the other hand, an item (say a printer) is offered for sale at a reduced price with a notice saying "leads missing" or "software and manual missing" it would be perfectly legal. These statements would form part of the description of the goods, and your contract with a retailer would be deemed to have been based on your acceptance of the missing items. You couldn't subsequently insist that they be replaced, or reject the goods as faulty because of the missing items. You could however reject the goods if another fault was present.
Does that help?
