Abstract: In response to receipt of a best-deal request specifying requested feature levels for products, feature sufficiency for each of said products is evaluated. Each feature sufficiency indicates whether or not a given product meets a respective requested feature level. Normalized prices are determined for the products. Products are sorted according to feature sufficiency and normalized prices for the respective products. A best-deal list is generated with product identifiers for the products arranged in the sorted order.
