Mail surveys would be the most cost-effective way to gather information from a large sample size of at least 300 people. It also allows for anonymity, which may encourage more honest responses. In-home personal interviews and focus group interviews are more expensive and time-consuming, while a marketing experiment and observation research would not provide enough specific information on the motives and desires of potential customers.
