Shopping goods are goods the consumer will research, and make value comparisons around quality, price, and style during the selection and purchase process. Convenience goods are frequently purchased goods the consumer does not invest a great deal of thought into during the buying process. The primary difference between shopping goods and convenience goods is the amount of time and effort the consumer will dedicate to the process of making a product selection / purchase decision.
Specialty goods have distinctive characteristics or unique qualities and/or brand identification for which some consumers are willing to make a special purchasing effort, like purchasing Hugo Boss shoes. Unsought goods are goods the consumer does not know about or does not normally think of buying, like fire extinguishers. The primary difference between specialty goods and unsought goods is the degree of consumer’s awareness of the product.
