It is the practice of selling two or more separate products together for a single price. This is usually done in case of goods which are sold as package. Like mobile phone with data cable, cover, head phone etc. it is of three types:
1.) Pure bundling: this type of price bundling is used where two products can be sold only as package. For example a new pen is always sold with its refill.
2. )Mixed bundling: it is used when the product can be sold separately as well as a bundle. For example pizza hut’s pan for four.
3. ) Tying: in this case a main product is purchased with the complementary product. Like nail polish is purchased with its complementary product nail polish remover.
