Highlight "Best Value" more clearly

Sellers frequently sell products in different package sizes which makes it difficult to work out which is the best value (two examples are coke and washing up liquid). It would be helpful to have a banner headline which highlights (best value) irrespective of pack size e.g. if an 18 pack 'cube' of diet coke offers better value than a 30 pack 'cube' it would be helpful if that were highlighted more clearly (as opposed to, for example, just searching for a 24 pack cube.
