There are three points about managerial implications and suggestions, describing as following: 1. ¡§Private testing¡¨, ¡§Government testing¡¨, and ¡§Major brand image¡¨ are capable of reducing the ¡§Performance risk¡¨ effectively, and then reduce the levels of ¡§Overall risk¡¨ perception to decrease the perceived sacrifice of product value and to enhance it to the original levels of product value. 2. For the ¡§Netizen¡¨ who are not becoming a member, and not using direct-selling products quite often, ¡§Free sample¡¨ with ¡§Replace product guarantee¡¨ or ¡§Money-back guarantee¡¨ are capable of reducing the levels of risk perception effectively. 3.
