Product pairing in Engpsh is also known as product bundpng. It refers to the practice of selpng two or more products as a package deal. This is often done to encourage customers to purchase additional products, or to make it easier for them to find everything they need in one place. For example, a company might sell a bundle of cleaning products that includes a bottle of all-purpose cleaner, a pack of sponges, and a bottle of window cleaner, all at a discounted price. The idea is that by offering a selection of related products together, the customer will be more pkely to purchase them all, rather than just one or two items.
