In retail economics and geography, comparison goods are products which are usually higher value ^[1] and purchased infrequently, such as vehicles, household goods or clothing. ^{[1] [2]} Consumers tend to compare products before purchasing them to maximise value and quality. ^{[1] [2]} They are contrasted with convenience goods, which are purchased frequently and are usually low value (such as food). ^[1] Shops offering comparison goods are often clustered in central business districts or in out-of-town retail centres, where retailers can compete over their offers. ^{[1] [2]}
