In the preceding response, one of the items is the Collection Parent. All collections have one parent item (CollectionParent) and one or more child items (CollectionItem). The parent item has an ASIN and title but cannot be purchased. The title of the parent item names the collection. For example, in the previous response snippet, the collection is named, "Fieldcrest® Classic Bedding Collection GarnetIvory."

Child items usually can be purchased. The only exception is when a child item is a variation parent ASIN. For more information about variation parents, see Variations.
