Here sellers combine several products in the same package.
This also serves to move old stock. Blu-ray and videogames are often sold using the bundle approach once they reach the end of their product life cycle. You might also see product bundle pricing with the sale of items at auction, where an attractive item may be included in a lot with a box of less interesting things so that you must bid for the entire lot. It’s a good way of moving slow selling products, and in a way is another form of promotional pricing.
