What do you mean by additional products?

Additional products generally refer to extended products, and extended products refer to services or values provided by products that exceed customers' expectations. Any product is composed of three layers, the innermost layer is the core product, the second layer is the peripheral product, and the third layer is the extension product.

Matters needing attention in implementing product promotion service:

1. Every value-added service will increase the cost.

2. Value-added benefits may soon become expected benefits. After getting used to a value-added service, customers will take this service for granted, thus reducing the value-added significance of this value-added service to customers. At this time, new value-added services should appear in time.
